Title: Review - Sigma 35mm f/1.4 DG HSM

This lens is simply awesome. It even blows away the Canon 35mm f/1.4 for a fraction of the cost. I'm sure Canon will make a better version soon, but at only $900 for such great results with the Sigma, will there really be any reason to pay Canon's way higher prices?

As red ring is not copyrighted (look at Samyang), Sigma should definitely put one on this lens so it sells well :D

I can't eloquently put into words how much I love this lens. It performs beautifully on my 5Dmk2 and 7D; it's the kind of lens you just leave on a 5D to bring everywhere. I'm in the middle of shooting a weekend of dance performances right now, for which I rented my other favorite lens the Canon 135 f/2. Both produce just awesome images on my 5Dmk2 at 1600iso f/2.2 1/800 under stage lights. It's good enough I'm probably going to sell my 50 f/1.4 for an 85 f/1.8 because I find I just don't use my 50mm anymore.

Justin, thanks for a great review.  It was a bit reassuring to me, as when this lens was released I really felt like I would get it at some point, but my desire for it had cooled somewhat.  I too am a fan of the 35mm focal length, so I may again look at getting this lens.

There is no reason to buy any other 35mm 1.4 from either canon or nikon. Why bother? If sigma made a 24mm 1.4 as good as this 35mm, I'll sell my 24L II and pocket the cash.

I've had it for eight days now. Couldn't be happier.

It approaches the Canon 135mm f/2.0L in just about every characteristic (betters it in none as far as I can tell) and it's far more versatile for me.

Only used it so far on the 5D3. Once the early elation wears down, I'll try it on the crop.

i've been struggling with my next lens purchase and i've narrowed it down to the 24-70ii and this sigma 1.4 (leaning sigma). clearly, price is not the issue - space in my bag is! i like to pack light, and i love 35mm. the question: do you guys believe the 24-70ii will outperform the sigma 35 at 35 f/2.8, or at least close and the added versatility makes the 24-70 a better choice? i generally prefer primes due to size/weight but everyone can't stop talking about how great the 24-70ii is, and i don't often shoot in low light but man, if i get this sigma i might just have to!

extra, relevant info: i own the 24-105L
and edited to add more info: shoot a 5d3

i plan on making the purchase after canon's apr23rd announcement - i know it's a long shot but i've been waiting for a 35mm 1.4ii from canon for a long time - what say you canonrumors? thank you in advance for your help :))

According to TDP's testing, the 24-70 II is better than Sigma 35 at f/2.8.

Man, tough comparison.  The 24-70 f/2.8 L II is not a light lens at all, it's optically incredible, with the price to match as you know. I could see you selling the 24-105 after getting it though, you won't miss the extra reach with the quality of image coming from the 24-70.

While I didn't do side by side tests, I do have some shots taken at 35mm on the 24-70 and they're pretty much perfect... so can the Sigma out-perform the Canon? No, I can't say that it would. But then, I'm not using the Sigma at 2.8... I'm using it at 1.8 - 2.2

The Sigma also isn't a light lens, though not as hefty as the Canon 24-70.  If price isn't an issue I'd say go with the zoom, you'll get a lot of use out of it. But I, personally, find a lot more joy out of using the Sigma... hope that helps.

They updated the 30 1.4 for crop-sensor cameras, and the 50, I think, was their first step in the right direction (it was priced at more than the Canon 1.4), so maybe throw a few more hundred per lens into a bit of a redesign, up the QC and maybe that's all it needs.

Thoughts?

I don't know about others, but I'm holding onto the 35L for now.  The price difference isn't that much of a factor since I already have the 35L (sunk cost).  The Sigma offers more value for those that don't have the 35L, but it does not compel me to change.  According to reviews (TDP), the Sigma peforms better toward the center while the 35L does better at the edges/corners.  I'll wait to see what the 35L II offers.  Right now, the 24-70II beats both the 35L and the Sigma 35.  Hopefully, the 35L II will do better than the 24-70II.  If not, I'll stay with the 35L.

I had the Sigma in my amazon cart at one point and almost bought it. Went for a 2nd hand 135L instead. So tempted now after reading the review!

How many lenses is too many? I used to think 5 was my limit. Somehow I want less lenses. Is that weird?

I thought my Pelican 1510 case decided how many lenses I had. If it fit, I own it, if not... shouldn't have it.

I have a Canon 40mm f/2.8 & a Sigma 35 f/1.4 that don't fit, but I'm not getting rid of anything either now ;)

It's pretty fascinating to read the reviews for the Sigma but as for a current owner of a 35 1.4L, it would be a cold day in hell before I ever gave my "go to" L lens. It's worth it's weight in gold as far as I'm concerned. I'm happy you guys like the lens but I'll never trade a Canon FOR a Sigma. Not in this lifetime.

Sigma's on a bit of a roll i got a 30mm for my m4/3 camera last year that is really good.

I wish they would update their 50mm too.  I had no interest in it until I tried the 35mm, which I liked so much I ordered the 50mm - only to receive a copy (brand new) that seemed to have every flaw I've read about.  So I returned it and decided to stick with my Canon 50mm 1.4 for now.

As for Sigma being on a roll, lenstip fairly recently gave a rare (for them) rave review of Sigma's new 180mm macro lens.  Has anyone here tried it?  (I've only tried their 150mm macro, which I didn't much care for.)

This isn't quite what you're asking for, but The Digital Picture's review includes a bokeh-at-f/4 comparison of this lens vs Canon's three 35mm lenses and the Samyang equivalent.

Good review, sounds like another viable option.  I've stayed on the canon path with regard to lenses except with my Tokina 11-16mm f/2.8 and I really like it a lot... only because of my experience with it, would I be willing to try something like this, but I'd have to try before I buy...  ;D
Title: Re: Review - Sigma 35mm f/1.4 DG HSM
Post by: marooni on April 13, 2013, 02:07:28 AM
I tested Canon 35 f1.4 (that I own) and Sigma 35 f1.4 (that I jumped to buy immediately) and Canon lens has a more pleasing bokeh and image. I made the comparison on screen and paper (1000mmx700mm printed images).

Truly, the Sigma looks crisper, but I prefer a general beter looking image.
I made this comparison because I could sell my used Canon 35 f1.4 at the price of a new Sigma 35 f1.4 and I almost made the switch, but then I said to try the Sigma first.

I decided to keep my Canon lens from two reasons:

1. Sigma did not demonstrated yet that can make a working horse (I had a Sigma 50mm f1.4 and was extremely unreliable). I can`t afford to have bad working lenses or on repair for weeks in a row. This will be a disaster for me.

2. The images printed looked beter from Canon. The colours and general image are more appealing.

In the last years  we are all looking at the numbers, but nobody looks at pictures anymore.

I got the idea that the Sigma is cheap, but I do not want cheap, I want the best Image and reliability.

And I am sure that all of you know what I am talking about.

Justin from your article "Vignetting is incredibly prevalent on this lens, enough so that you may have to adjust your metering accordingly." What aperture did u use on the last shot in the review of the boy reading? I suppose one could just crop a bit or as u say use post editing to wash away the added imperfection. Funny that proprietary s/w enables people to add vignetting but that's another story. I really loved the shots and the other pro shots I've seen with the 5D3 are incredibly sharp and the color tuned to "what that can't be" level. Wish I could get those results. Checked out your Huff review and the pros who liked your stuff on Flickr, Best of luck with your career and being a "stay at home dad". :)

That image was taken wide-open at 1.4, I was attempting to see what kind of flare could be produced with light going into the lens (I believe I took the hood off too). You can see a bit of green flaring, but not much else beyond that, and the image remains sharp and contrasty.

Sorry to sound like a therapist, but what I hear you saying is:

1. You prefer the look of images you make with the Canon lens.

2. You've had a bad experience with Sigma and don't trust them.

It approaches the Canon 135mm f/2.0L in just about every characteristic (betters it in none as far as I can tell) and it's far more versatile for me.

It could not be farther apart from the 135L. The 135L is a bokeh machine, while the S35 is not, to put it mildly.

Colors on the left are more vivid. Background on the right is more pleasant to the eye. Is the Sigma on the right?

Thanks.


OK , I took these few minutes ago, same parameters.
Now there are differences in the red colors, one camera can not separate red/orange colors as the other, mainly because of the CFA and also the profile.(we can take a color profile discussion later so all understand what a profile does or not with the bokeh, contrast curves, colors  etc  who plays a major  role in what we think us se, or not )

Now to the background
which one do you think is more pleasing than the other? here are the same parameters regarding contrast curve=linear  and the same adobe profile are chosen

canon 35mm and sigma 35mm both at F 1.4

OK...what I have become a big "fanboy" of is Justin's reviews. They are fantastic, along with the images he includes.
Love the shot of Trevor (and thanks for the lighting info).
I own the lens and it is simply the best 35mm on the market for a Canon 5dIII owner, (the great price is just a bonus).
It is a joy to twist this glass onto the front of my rig. (No winking needed). Who cares if Canon updates their 35L!
(I figure with the $1000 I saved I will pick up a 135L next week when the rebate kicks in!).
Unlike Justin...the only complaint I have is the useless toaster-cozy case? WTF? A big square lunch case for a sleek round lens???? Go figure. That thing went right back in the box as soon as I took the lens out. What would be nice is a custom-fit, sleek neoprene case. Keep it simple.
I also own the Sigma 50mm and although it is not at the level of this new 35mm I am very happy with that lens, too. (Guess I got a good copy... I covered the unsightly shinny gold ring with pinstriping tape, no...not red,  just for fun and to confuse enthusiasts! LOL!).
My only question is: Dare we expect more of this from Sigma????

OK , I took these few minutes ago, same parameters.
Now there are differences in the red colors, one camera can not separate red/orange colors as the other, mainly because of the CFA and also the profile.(we can take a color profile discussion later so all understand what a profile does or not with the bokeh, contrast curves, colors  etc  who plays a major  role in what we think us se, or not )

Now to the background
which one do you think is more pleasing than the other? here are the same parameters regarding contrast curve=linear  and the same adobe profile are chosen

canon 35mm and sigma 35mm both at F 1.4

This is a closeup, almost a macro, and the image on the right is taken from a slightly closer distance (maybe due to the different lens and the different body). As a result, the background on the right is blurred more, and you can see the different perspective. Also, in closeup shots, the effective FL changes a lot, the f stop changes, etc.

Testing non-macro lenses in such closeup situations is not such a great way to evaluate a lens. BTW, next time you do that, do not put the other camera in the frame!  :)

Sadly, both lenses have no weathersealing. I think it's a shame to shoot with optics worth a grand and they get spoiled in the first rain. I think the producingcosts of some siliconrings can't exceed more than a few bucks. Of course the design would be a little bit more complicated, but this lense is meant to be superior...

It even would push canon a little bit more to produce a Mark II of their own lense, for a fair price.

Hi, one time I had similar problems, seems like some pgms create .jpgs that the CR website cant handle. Try to download a jpg from the site and then post it again. You know that jpg will be OK. If it works then just modify your post. Now, what exactly the problem is with certain jpgs, who knows?

"Spoiled in the first rain"???  Do you really think these lens are THAT delicate?  Admittedly, most of my kit is weathersealed, but I have shot with non-weathersealed lens in a lot of crazy weather and have yet to have a lens be "spoiled in the first rain".  I think you should always exercise caution and protect your gear as much as possible, but I don't think either the 35L or the Siggy are quite so delicate as that.

If we are looking at something subjective as Bokeh the contrast curve and many other things plays a major role
like the profiles we are using , behind is a Husqvarna  (Husky) motor saw and the color is orange, here we can see how adobe standard + linear curve represents the orange as red ,  on the right is a custom profile for my Canon camera  created with qp-card+linear curve , the same raw file are used, colors, contrst curves etc plays a major role in what we call bokeh, not only the lens.

How does it compare to the Adobe camera profile?

same here, notice that I have the both lenses and are a little bit allergic to peoples statements when they not have a clue what they are talking about and have not tested the lenses against each other
So here comes two new files. Which is best regarding bokeh ? f-1,4 from sigma and canon and the background
I see clearly green ca from one of the lenses, is this to short or to long from the sharpness plane and to the  back ground?
The only thing deserving attention here are the letters on the bottle: "TRE" and "47". The Sigma is much worse, as expected. The background is blurred enough not to matter.

please explain, you do not se any difference in CA? one lens is much better corrected than the other

Because in normal viewing conditions, the CA is not visible. On the other hand, the double lines are, and can dominate the whole picture.

Look at this:

(http://farm9.staticflickr.com/8512/8499652513_c9508a78d0_c.jpg)

Do you see CA? I do not (but there is, at 100% zoom). What grabs my attention are the double lines on the back.

Let us say that I tested the same lens with closeups. Like those here:
(http://farm9.staticflickr.com/8397/8649676688_65a4dd5227_z.jpg)

(http://farm9.staticflickr.com/8375/8499684101_f32ae0436c_c.jpg)

Look good, right? Based on those closeups, you would never say that those double lines could be a problem. But they are. And I have many shots on my HD with double lines, and many more without them.

All those shots are with the 35L on FF.

not visible?
canon 35/1,4 is known for ca and at 1,4 .http://www.photozone.de/canon_eos_ff/516-canon35f14ff?start=1 (http://www.photozone.de/canon_eos_ff/516-canon35f14ff?start=1)
the sigma is better corrected and also also known for that
give me 2 exact same exposure from the two lenses.

now, because of  different contrast/resolution  in the lenses  there can  be different results.
which one is better than the other?

If you shoot charts, disable the lens corrections and look for CA, it might be visible. Do you see it in any of the shots I posted?

The most visible difference above is the contrast and the colors.

BTW, there is nothing wrong with the CA correction with the Sigma, Canon should do the same with its 35LII. But the Sigma is more corrected lens (not just for CA). This made it sharper but screwed up the bokeh. Canon did exactly the opposite with the 50L and the 85LII. The 50L is much softer than the 35L but it has much better bokeh. The 85LII has stronger PF than the 35L but much better bokeh.

Where is the CA here:

again you are showing some pictures with out any comparison,  I have  a different view about the  two lenses  also dpreview,lens tip and photo zone  have tested the sigma and have i different opinion  than you have..
not much more to discuss, or what do you think


The Sigma has the best results of all 1.4/35 lenses, tested by us so far in the categories of resolution, distortion, chromatic aberration and coma correction. It also fares very well in the case of astigmatism correction and the autofocus accuracy, being one of the cheapest lenses in this class of equipment. I think I don’t have to add anything more…

Nothing about bokeh there.

It is OK if you do not care about it, but you should not dismiss my concerns just because Klauss liked the lens (but not the bokeh). Keep using it in real life, and you will see what I mean.

I have done it now for some  weeks now ,  compare the lens with my 35/1,4 Canon, as I said, we have a different view and I think my pictures shows that 1. the  sigma lens has higher resolution 2. there are no difference in bokeh , except that sigma has higher contrast. So I leave you with that we have a different view of the two lenses.

Fair enough. Thanks for posting those comparisons. Even though they are not what I wanted (focus too close), I can still see a confirmation of what I expected.

I do not need to sit around testing lenses...I let professionals do that for me and I read their results. The results lead me to buy the Sigma which is easily $400-$500 less than the Canon and rated superior by all the pro reviewers, not a weekend warrior. Also, to read Justin's review, a review from a VERY COMPETENT real world photographer just puts it over the top for me. My Sigma is an incredible lens. The price is amazing. If Canon comes up with update, the price will approach $2000. So the purchase for me was a no brainer, and I have been out making images with the lens, in the real world and have been nothing but pleased with my decision. Great lens!

I own the 35 L.  Last night I got to try the Sigma at a wedding I was shooting.  Wile there were no direct, same comparison shots, the shots I took are virtually indistinguishable in a real world shooting situation.  I have to look at the EXIF to see which shot is from which lens. 

Of greater interest to me would be the makeup and design of the internals.  I know the Canon is a workhorse, having shot it for years without issue.  Will the Sigma withstand pro level shooting for years, in all conditions?  Has someone disassembled one to observe?  Are the moving parts quality or not?  My frame of reference would be the older Canon 24-70 L which had internals notorious for wear under heavy use.  While those are replaceable with service, other lenses are much better constructed.  The Sigma certainly feels as good as my Canon.  What would we find under the hood, though?

Thanks, ankorwatt. I don't think I fully understand all you're showing us, but it's interesting, and a good learning experience. I appreciate your professional efforts!

I tend more toward infared's inclinations -- just looking at results I get when I'm pushing the shutter button. Since most folks say it's as good or better than the Canon version, I figure I've saved a lot of money if nothing else.

As for the question of internal components holding up to everyday professional use, I guess we'll have to see. Not an issue for me as I'm not using it that way.

The results from the Sigma do look good; I've never really been an ultra shallow DOF shooter so perhaps that's why I can't think of any situations when you'd be shooting at f1.4 and require critical corner sharpness.

Can someone post a real picture which has razor thin DOF but requires corner resolution ?

It's a matter of framing. Sharp corners mean you can frame the scene as you like, compared to center framing + cropping.

you will never get critical corner sharpness at 1,4 but it shows that sigma in this case is much better than canon at 1,4 which not can be bad parameter.

you seems to   have trouble to understand that the sigma can be good as the canon

You have trouble understanding that both can be bad, as I and many other people demonstrated already. If you blur the background enough, as you did, you will see no essential difference. I told you that a few days ago.

Try to challenge both lenses. Look at the other thread for examples of bad bokeh. DO NOT FOCUS CLOSE! Use the lens, well, the way you will use it. Instead of a miniature, put a real person there.

Your "several distances" are too short. You concluded that both lenses have wonderful bokeh, which is incorrect in many situations. They typically include shooting half-body environmental portraits, not miniature toys; and not always wide open.

Pi, ankorwatt says, and pictures prove that, the Sigma has not worse bokeh, than canon has, despite it has less CA and is sharper - optically better. No more, no less. And no one says the bokeh of 35 mm f1.4 lens is as nice as 70-200 f2.8 II or 135 f2 for example. But from 35 mm f1.4 lens bunch it is the best one.

What I have found is that  the bokeh is very similar, the Sigma render the back ground little bit smoother, the Sigma lens has higher sharpness/resolution  and good resolution in the corners even at 1,4  where Canon 35mm  is very soft.

Speaking about corner resolution wide open - not that it really matters - can you find any confirmation of what we see here:

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=829&Sample=0&FLI=0&API=0&LensComp=121&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0 (http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=829&Sample=0&FLI=0&API=0&LensComp=121&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0)

It is a bad case of astigmatism: the Sigma has very poor vertical resolution and very good horizontal one. The Canon is much more uniform but it has lower contrast (which I can confirm - there is some diagonal, comma-like smearing).

I'm not seeing TDP result reflected in the pictures posted by ankowatt - again. I say again because I started a thread about inconsistencies between test results from TDP and photozone, citing the 70-300L as an example, but no one was interested.

ankorwatt's examples show the Sigma to be far better in the extreme corners than the Canon 35L, more so than you would guess from the TDP results. However my guess is that photozone will make the difference very clear. As I stated in an earlier post I wouldn't change my 35L because of soft extreme corners at f1.4 anyway

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=829&Sample=0&FLI=0&API=0&LensComp=121&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0 (http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=829&Sample=0&FLI=0&API=0&LensComp=121&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0)

It is a bad case of astigmatism: the Sigma has very poor vertical resolution and very good horizontal one. The Canon is much more uniform but it has lower contrast (which I can confirm - there is some diagonal, comma-like smearing).

I'm not seeing TDP result reflected in the pictures posted by ankowatt - again. I say again because I started a thread about inconsistencies between test results from TDP and photozone, citing the 70-300L as an example, but no one was interested.

ankorwatt's examples show the Sigma to be far better in the extreme corners than the Canon 35L, more so than you would guess from the TDP results. However my guess is that photozone will make the difference very clear. As I stated in an earlier post I wouldn't change my 35L because of soft extreme corners at f1.4 anyway

The results may depend on where you focus - in the center, or in the corners. Not that I will ever focus in the corners. TDP focus only in the center.

BTW, the 35L is the best focusing lens I own or even tried; and this includes 20+ lenses. I would think twice before I let it go, when the 35LII materializes. I get consistently good results even with the outer AF points of the 5D2, which we all know are useless.  ;)

I did not ask you for numbers that I can find myself on the web. I asked you if you can confirm what I see on TDP. If you do not want to do the test, fine. I did not say anything to defend either lens. You are too sensitive.

BTW, this numbers do not distinguish between horizontal and vertical resolution. My guess would be field curvature, and with proper focusing, I expect the Sigma to look better that on TDP, and much better than the Canon. Does this sound as a defense of the Canon? :)

I agree so far the sigma 35 has been an outstanding lens for me
also I thinkt he sigma renders colours a little warmer which I like, maybe 200K on the lightroom slider

Many times I can't tell a good picture from a not so good picture, my eyes are not so good and I am not skilled enough. Having said that I am still very happy with my 35L. I think it delivers great character in the images I capture, maybe the Sigma is better but I still wouldn't make a change as it simply doesn't makes sense. First of all since it's not a priority, I have other priorities gear-wise, secondly as I have said before, the 35L has proven itself over soon 15 years, we still don't know how the Sigma will keep up over years of hard use. But competition ie always good and I hope Sigma keeps launching new exciting lenses to push both Nikon and Canon to improve even further.

While I can appreciate all the technical stuff, after a while it does grow wearying. Almost like arguing that one fish hook will catch more fish because it has a sharper point and its barb is 2 millimeters longer.

Today I did two events, around 1000 pictures, almost all with the Sigma 35mm. It makes me feel almost giddy with joy. On a 5D3, it's like there's no picture beyond my reach (at least within the focal range limits). I'll bet if I had a Canon 35mm I wouldn't feel much different -- but I do love this extra money I have!

+1. Well said. I also believe that tough competition will make Canon better. We are not talking about switching a system for another, but for some a lens. Canon shooters have bought third party lenses all the time (i.e. With the understanding that people give up quality for a lower price), but what seems to to be hard for many is that it now seems that this particular third party lens is actually better than its original counterpart...

Another can of worms altogether :) I am not knowledgeable enough to pass judgement on that matter, nor do I want to. All I know is that it is more than good enough for me as it is now. I truly do not believe that it is the "inferior" sensor from Canon that is keeping me from being great! ;)

dilbert. I also find his comments on Canon ahead in offering 'bells & whistles' strange, because Canon really offer less of this - IMHO - of course.

Yes, and massive investment into R&D for companies that don't profit as much as Canon are a way to avoid bankruptcy. I'd be even more scared of owning a Nikon or Sony in this day and age. Sony also doesn't have the best track record for releasing products that are both successful and groundbreaking ;) Uhh...Betamax anyone?

And I am sure that all of you know what I am talking about.

Sorry to sound like a therapist, but what I hear you saying is:

1. You prefer the look of images you make with the Canon lens.

2. You've had a bad experience with Sigma and don't trust them.

What I don't understand is your "wink, wink," you know what I'm talking about. Is there something you've said that I'm not hearing?

What everybody knows is that Sigma is a cheap brand and until now their lenses had problems with front/back focus, build quality, quality control, etc. I hope that Art lenses will be different, but this has to be demonstrated. 800 $ for a 35f1.4 with this performance is a great value, but you have to take into consideration the bad reputation of the Sigma brand.
Do you think they changed the quality control over night?

I tested Canon 35 f1.4 (that I own) and Sigma 35 f1.4 (that I jumped to buy immediately) and Canon lens has a more pleasing bokeh and image. I made the comparison on screen and paper (1000mmx700mm printed images).

Truly, the Sigma looks crisper, but I prefer a general beter looking image.
I made this comparison because I could sell my used Canon 35 f1.4 at the price of a new Sigma 35 f1.4 and I almost made the switch, but then I said to try the Sigma first.

I decided to keep my Canon lens from two reasons:

1. Sigma did not demonstrated yet that can make a working horse (I had a Sigma 50mm f1.4 and was extremely unreliable). I can`t afford to have bad working lenses or on repair for weeks in a row. This will be a disaster for me.

2. The images printed looked beter from Canon. The colours and general image are more appealing.

In the last years  we are all looking at the numbers, but nobody looks at pictures anymore.

I got the idea that the Sigma is cheap, but I do not want cheap, I want the best Image and reliability.

And I am sure that all of you know what I am talking about.

no , sorry I don't

please show me, I have  both canon 35/1,4 and the sigma 35/1,4

Might be because you did not own a Sigma before.
I owned "the 50mm" from Sigma and it was so unreliable. The "internet" is screaming of the problems that Sigma lenses has.
If Canon, Nikon, Zeiss, Sony charge so much for a high performance lens, how Sigma did it so cheap? Has to be something wrong inside. Something that will crack when the lens will have to hork hard.

He is saying that on close subject ( 1m and closer) the lens is amazingly sharp, but if you try to focus on something further than 3m, the the focus is out of control and for him was imposible to micro-adjusted. He likes the lens so bad that he never think to retur it and in the same time is totally frustrated by focusing.



Anyone else had this problem?

My copy was already very sharp on both close ups and longer distances when I received it, and after AF micro adjustment it got even better, with simultaneous improvement on all focus distances. Your friends copy is faulty and he should return it, which shouldn't be a problem as it's only a week old.

I'm very pleased with my Sigma 85mm 1.4 and will probably get the new 35mm at some point however I do wonder if Sigma have produced the docking gizmo to get around the fact their quality control appears to be, um, lacking if you read/believe the various posts on the net. Instead of having customers returning new lenses for exchange or service centre tweaking, the customer can do it themselves by correcting for four different focus points via their gizmo.

Sounds like Sigma might be putting the solution to their own problem into the hands of the customer and this may fool some customers into thinking that Sigma are being "customer focussed" (no pun intended). Maybe Sigma should sort out quality issues at source rather than after the purchase has been made?

Just a thought.

it could be, but i've gone down the road of sending things to sigma for calibration, and i wouldn't do it again. I'll take this USB dock any day over that. also it looks like they will be able to tweak the firmware with this dock as well as AF, so i think the days of rechipping your lenses are behind us. Besides, i've had to send lenses to Canon for adjustments as well, so while i think sigma's QC might be problematic, canon's isn't perfect either.

The idea of adjusting in several places sound very interesting. But with the software not controlling the lens while adjusting, not even being in the camera, how do one know how much need to be adjusted without making 200 tries?? What means -1 or +3 ??? How much distance is that? How you know what number to put in there?

That is my concern.  It seems like a lot of trial and error, and shooting charts many, many times.  Fine if it is the only lens in your kit, but seems like a pretty huge investment of time. And what if, like many of us, you shoot multiple bodies?  I like the concept of the finite focus control; I'm less crazy about the time investment.  Doing AFMA on a few bodies is already a fair investment of time (I do it manually). 

One plus, however, is that unlike the slow, multi-step task of making each change in the body, the software at least allows for quick adjustments.  It would be great if the hub came with a FoCal type software that could automate part of the process.

Ask yourself this, "if I have to adjust my new lens up to four times over its range to ensure sharp focus, do I feel I've wasted my money?".

Having just used Focal for the first time the other day I agree with that. I would love to have four adjustment points on my Canon zoom lenses. At least Sigma users now have that chance! All you need is the data from Focal and you're set!

I tested Sigma and Canon side by side. In the end I chose Canon. First sharpness is not everything, and overall pics from Canon just seem a little bit more pleasing. Second Sigma AF is a bit less responsive, and it misses more in dim light (which is the biggest factor). And last (but not least) new Sigma just doesn't feel right. It's like Batman first batch of helmets - looks kewl, black and shiny, but when you smack it, it cracks open. By which I mean the plastic feels cheap to touch :D

I had a chance to finally try the Sigma out and it looked cool, it felt heavy and big for a 35 f1.4. Loved the focusing ring, very good color and contrast. I used LV to focus, since it wasn't afma'd, and I wouldn't trade my 35 L for it because of sharpness, others will. But all of that wasn't really important. I wanted to see if the AF is indeed "same as the 35 L" as I've seen claimed, I have always doubted that, because the 35 L is fantastic. And I was right, the AF of the Sigma feels like the 35 L in slow-motion.. VERY slow... I'm not sure if people who have tested the Sigma vs 35 L have used a 5d, and the 1d X spins the 35 L faster because of the higher battery voltage, but it's not even in the same leauge as the 35 L.

So I'll take my small light, VERY sharp, superfast AF 35 L a million times over.

While i took the family to a circus yesterday i accidentally gave the sigma a good whack on the aluminum bleachers. It was a pretty forceful blow and i feared some damage. i actually muttered a foul word while in the company of lots of kids. not a scratch. fingers crossed, let's not do that again....

IMHO, because Sigma has been at the lens game for a while, the proto-Batman analogy is clever but not really appropriate in this case.  I left the 35mm out on my desk for a week, just to stare at it.  I believe it is a thing a beauty.

Ankorwatt: I might be missing something here, but I get the impression that your comparison pictures are made with a 35L on a Canon body, and the Sigma on a Nikon body. Is that correct?

If that is the case, then I think your comparison lacks something, color rendition etc might be affected by other things than the lens... :)

That said, I would get the Sigma if I would choose between them. I would do that even if it was 90% as good as the Canon, as I am one of the price sensitive ones...

But now if it is 105% of what the 35L is (better sharpness, worse AF etc.), then the choice gets even easier.

I also rarely take pictures at 35mm that requires blistering fast AF, I am usually at 70 at above when that occurs. (although I see the point with kids at home)

put it this way i got a brand new sigma 35 f1.4 and a 2 year old used canon 135 f2L for what a canon 35L would have cost me
I think the IQ out of the sigma beats the 35L although i have only tested and not owned the 35L
still thats not saying the 35L is not a great lens i almost pulled the trigger and bought one the day sigma anounced the 35!

pleasing
less responsive
misses more in dim light

sounds very un scientific

the sigma skates 8 around my canon 35/1,4 and also nikon 35/1,4

Why does an opinion on a lens (or of the images that it is capable of producing) need to be scientific? Numbers are not everything. I am currently tackling the issue of which lens to get at the 30 or 35mm focal length. Whilst the Sigma is undeniably sharp, after spending alot of time comparing images from the two I find that I like the character of images produced by the Canon more. Unscientific perhaps, but I am neither a scientist nor a robot.

Post by: Viggo on July 25, 2013, 02:36:33 AM
The main difference between the two can not be seen in pictures. The AF-speed, where the 35 L is superior.

Although I always loved my 35 L I can clearly see, after using the 2470 II for a while, the color and contrast isn't all that awesome on the 35 anymore. I just sold my 35 L today, and no, I will not replace it with a siggy, I have something else in mind.  8)

Anyone know why the Siggy isn't weather-sealed? A disposable camera for 10 bucks is sealed to ten meters, seems strange a lens with no extending parts can't be sealed to handle some heavy rain without braking the bank.

Around here the Canon 35mm f/1.4 L costs 5,900 NIS, and the Sigma costs 3,600 NIS. so I could save ~40% and get the same image quality? Sweet...

Some will need the weather sealing, but others could use the different to buy another lens, say an EF 100mm f/2.8 Macro USM.

The siggi and Canon 35 f1.4 are not the same and never will be. They have different renderings and bokeh. Colour and contrast are different too...as is flare control and AF competency. Get a Siggi 35mm on it's own merits, but don't kid your self it's a 35L clone, it's not. There is a beauty in the 35L which only comes out in the pictures it produces. Most skilled photographers who regularly use one fall in love with this lens for that very reason.

oh except to attach to the sigma dock for calibration :)

its still a stunningly great lens but I'm just loving the 50 so much at the moment. I will get around to using the 35 again though. I did find the 35 a really nice 56mm equivalent on my EOS-M though too

My 35 lives on the camera.  It is insanely sharp, and the focus nails it every time.  I had been waiting for the 50 to come out, but I bought the 35 on sale at Christmas.  I am glad I waited.  It is a perfect length for general shooting, and I can always crop when I need to zoom.

The 35mm A arrived today. It required only +4 AFMA on the 5DIII and -2 on the 70D, by FoCal. The consistency of focus on both is 99.2%, which is better than any of my other lenses. It has a nice balance on the camera, has a an exactly fitting bayonet mount, and feels very well made. The first shots are very sharp. Downloaded the DxO module and it removed the vignetting at f/1.4 nicely. So far so good.

The Sigma 35 is indeed very sharp. However, I tested it carefully against my old Canon 24-105 L at 35mm, using an iso 12233 chart. The 24-105 is sharper (at f/4 on both)! This is the second time the old workhorse has outshone the new pretenders (last time a Tamron 24-70 VC).

The Sigma 35 A is reported by Photozone and lenstip as having significantly superior MTFs to the 24-105. Either I have been unlucky with the Sigma and Tamron and getting poor copies or I have been very lucky and have a 24-105 which is an outlier in the right direction.

that must be one super 24-105mm you have there. i had one and we got along okay for a while, but it was replaced with by the sigma. when i got the sigma i did some rough test shots to compare them, and the 24-105 just had to go.

The Sigma is one hell of a lense but get's partly beaten by the Samyang 35mm 1.4, especially in the corners. It's sometimes interesting to see how other good competitors are getting less known if someone hypes the new one ;)

If you're willing to pay some attention on the pictures and you're not afraid of manual focus (but therefor with a fantastic focus-ring), you can get the samyang for a fraction of the price.

If you have a great photo, you are not really going to "see." A difference between the  Sam Yang and the Sigma. Me..I will take my Sigma and the AF every time. It a way more capable lens for more types of photography.

Okay

First off, I'm a new member and I don't see any buttons to start a new thread so I'll post my question in this thread.

I recently bought a Sigma 35mm 1.4. It's been great so far but i had a question about sharpness. I've been pixel peeping too much and have become obsessed with making sure my "copy" is good. Reading some negativity on the lens online made me paranoid. I just need a second opinion on whether my images are as sharp as this lens should produce. Focusing up close, the lens seems to be super sharp. When I have a further subject, it loses some detail, but im assuming this is because of resolution and megapixels? Other than sharpness, the lens isn't too great at focusing. When auto focusing at the wall right in the center from pretty close, it would miss over half the time. But it seemed to miss in the same way. Perhaps getting it calibrated at a shop will help?

Here are the images. They were shot on a 60D

They are all shot at f1.4 except for the last which is 2.8.

Photozone miss out the sweet spot of the 24-105L; they test at 24 and 40. I too find the 24-105L to be really excellent between about 30 - 35mm, from f4 to under f8. In fact that lens is unfairly maligned often as not. Switch the IS off, put it on a good tripod, ignore 24 mil and it's a fine GP lens, even for landscape.
