Although to be fair, maybe lentip is just clueless when it comes to taking shots. I do have to say that many first samples even from great Canon lenses and bodies have looked like trash. I'm always amazed who they so often end up putting their stuff in the hands of to produce show off first samples, since it seems to be people who can't get a sharp shot out of a 135 f/2 at f/5.6 even center frame and who somehow end up making ISO100 shots appear as if they needed and had applied NR suitable for ISO25,600. And then as soon as the equipments gets in the hands of any old random joe blow in the forums and suddenly the quality looks 10x better. I don't get it.


OK...I appologize....my previous quotes were from looking at the images on my iPad with Retina display...(sorry...I won't do that again....it is a non-scientific experience when it comes to viewing a photo file!!!!!)...I am on my desktop computer right now....I agree with you...EVERYTHING looks SOFT...like REALLY soft....I think something is amiss here.... I think we all REALLY need to wait for another review....Roger...(at Lens Rental...can you help us out here!!!!! LOL!).  I am going to throw these samples out as an error...and keep an open mind about the lens. Something is just not right here.

Oh boy....this does not look too exciting. the CA looks really bad (red box photo)...and the sharpness/micro contrast definitely has no WOW-Factor from what I can see in these images....that is for sure! (This preliminary set of images has more of an impression of the "Old Sigma").............makes my 24-70mm f/2.8 II as though it is worth the coin I dearly paid for it.

My screen at work is not the best, but I didn't spot such terrible CA. Are you talking about the red post box?

Yes...zoom in on the white lettering POCZTA on the left side of the box...I am looking on an iPad...I will have to check this out on my iMac later...but in general...there is no WOW factor with this lens....it has to have that or it won't sell....just buy the Canon otherwise...it's as good or better and less expensive. Simple.

Glad to help.

Posting this way, other people can click on the image. This increases the numbers of views on Flickr and makes you feel good!



It would be a concern if the clicks brought in money. Not so if the only beneficiary is my ego.

FUNNY comment!
I will stroke your ego a little more and tell you that this is a great shot! Nice freeze frame.

Never been impressed with the Canon 24-105mm L.  It's good but not worthy of 'L' status IMO.  So I'm very interested in this lens.  At an eventual street price of $650 more or less, it will be very interesting.  And great to have a worthy alternative to Canon.

It will take a loooong time before this new lens hits that price! The 35 1.4 hasn't budged much in price since day one. At the most it will drop $100. All recent Sigma lenses seem to be priced around the same $800 ish mark. It's still a lot of money for some, especially considering there is no weather sealing.

I'm relatively happy with the Canon version, bought it 2nd hand. Weather sealing and 77mm filter thread is more useful for me so I'll stick. Interesting prospect though for those looking at buying a general purpose zoom right now. A 6D or 5D3 with this thing would likely be a winning combo!

I agree with ZV....the price on this new Sigma is not going to drop to $650 anytime soon...sounds like it is very fairly priced in the $800 range.....I sold my Canon version and bought the 24-70mm f/2.8 II which is overpriced but great....IQ on it blows the 24-105mm away...but damn do I miss that extra reach...it is considerable!

OK...this is funny...4 posts back on the rumor homepage is the canon 24-105mm alert for $639... That is quite a bit cheaper...plus the Canon has IS.  I am a little slow on the uptake sometimes...but the Sigma has no IS...correct?
I owned the Canon and it is a very decent Zoom lens ...especially at $639!...
I am A Sigma Fan...own the new 35mm....but I am wondering if this lens really best the IQ on the Canon "significantly" asit will have to to sell well, right?

The sigma has stabilization. They call it 'Optical Stabilizer' (OS) instead of 'Image Stabilizer' (IS).

Thanks LuCo....somehow (I read three different right-ups and missed that info!!!)....The write ups I have read have DG in the name...but not the OS?   THAT is important to include. I apologize for my oversight. (don't get old...everything gets confusing!!! LOL!)/

I am not trashing the lens. In fact if the IQ is greatly better than the Canon version then I believe that I will buy the lens. 

I am pointing out, however, the big elephant in Sigma's room.  They have begun producing some very impressive lenses, and producing them quite rapidly. But their cameras are just so weird that they do not seem likely to gain nearly the market share on the bodies that it seems plausible they may gain gain on the great lenses.  Maybe they need to make a sensor deal with Sony like Nikon did, and produce a line of "straight" cameras if the Foveon thing never fully catches on.  Or make their own.  Maybe a non-bayer approach like Fuji is using.

Just as a point of order, this post has nothing to do with Sigma cameras. This is about their new lens.

As for the new lens I'd be more wary than I would with primes. Given the experiences I've read with the Sigma zooms, the AF may be much less reliable and accurate throughout the range. And you will surely need to have their lens dock to do the calibrating work -- adding more to the cost if you don't already have one.

Personally, I hope they have produced a real winner. I have their 35mm f/1.4 and it's my most used general purpose lenses.

Good advice about the zoom...although it seems that Sigma is really making a MUCH better effort these days.
The 35mm is SWEET~

Well..it definitely does not look like the Sony lens posted above...other than it is black and white...but it could be a lens that Sony is testing?
Really can't tag the camera body at all...so it is very hard to guess.  Interesting how the black band (zoom ring?), in the middle is so tight and indented from the white lens barrel.  It is, to say the least, unusual looking???!!!!!
Is this a clip from a bad, old 70's movie and perhaps we should be looking backwards ...no forward for a rumor....LOL..just kidding.

EOS Bodies / Re: Sensor Dust - DSLR vs Mirrorless
« on: October 23, 2013, 12:17:56 PM »
When you open and close Petri dishes for bacteriology you learn to minimise any chance cross-contamination by spores and airborne bacteria by having the lid plate always pointing its inside surface down and turning over the bottom plate so that the agar is pointing down. That way, particles do not settle on the inside.  I do the same when changing lens...

Ever considered carrying around a portable HEPA laminar flow hood?   ;)

This is my favorite response, above...too funny!

I have 2 MFT cameras and a Canon 5DIII.  I don't have dust issues with either type of camera.  I know that it makes sense that the exposed sensor on the mirrorless would welcome debris but I am not coming across anything that is monumental... i.e. that I am seeing in my images.  I use common sense when changing lenses and occasionally give the blow out treatment with a dust blower....but I do not see scads of dust that I need to PhotoShop out etc. in my images.  Do anyone really have a consistent problem with this?????

That is my quote "as good or better"...  I read a review BEFORE I bought my lens (I just looked for 20min and cannot find the review...but I did read it) and there were sample photos showing less color fringing with the 17mm TSE II with 1.4X compared to the 24mm TSE.  I was in shock.  In any event ...I have shot images with the 17mm TSE II alone and with the 1.4X on the lens.  I am very critical about image quality...I have to say...unless you are a professional Architectural Photographer and use the lens daily...or desperately need the f/3.5 for some reason or the slight extra swing/tilt..I cannot see buying both lenses.  The results are really SURPRISINGLY fantastic with the converter on.  It is something I would never even considered doing until I read the article. 
So, raise your eyebrows if you want ...but it is a great setup.
I'm happy for you for you enthusiasm over your 17mm setup, you have good reason to. But the review you refer to must be against the old 24mm TS-E. The version II is optically nearly perfect. Extremely sharp and sharper than the 17mm, CA, flare, distortion and vignetting is very well controlled and color and contrast are absolute top notch. And so is the 17mm. The pixle peepers will probably give the 24mm the highest grades, but to me, the quality differences between the two are academic.

I had not tried the 17mm+1.4xIII combo before, but did yesterday. It works surprisingly well, but the results are not as good as those you get from the 24mm TS-E 3.5L II (the differences are more than academic here). I did not do a very thorough test of how much tilt & shift I got from one compared to the other, but it seemed the 24mm gave me more of both. I'm sure someone else in here has done the comparison.
OK...this is getting interesting....I think that I stand corrected that The review I read MUST have been comparing the  17mm II+1.4X III combo to the OLD 24mmTSE
So Eldar, thanks for checking that out and giving a personal report (I would but have no 24mm!). Question...did you compare with the lenses stopped down to 6.3 or 8?
The reason I ask is because if you take a look at the DigitalPicture Lens Comparison Tool (only web comparison that I can find),  the results look VERY close. (Like say in a 20" x24" print are we going to see a difference?)

Any pics you can post?
I also apologize for my "perhaps" over enthusiasm.
I just left on a business travel (currently sitting in an airport lounge), so it will be some time before I can post anything more than text.

In the TDP ISO chart comparison I think it´s clear that sharpness and contrast has taken a fair hit on the 17mm/1.4xIII combo. But the interesting question is of course what you would say looking at an actual image.

To compare with something else; Reuter published the statistics for the 100 best images of the year (2012). Which cameras, lenses, shutter speeds, ISO etc. was used. The most widely used lens was the 16-35mm f2.8L II. And it is beyond question that they have plenty of good images to choose from. If you compare the 17mm/1.4xIII combo to the 16-35 at 24mm f8, you´ll see that your combo is at least as good as the 16-35. So equipment wise you are positioned to produce image of the year quality with what you have.

That was my point..hit the sharpness and contrast a little with PS and who will know the difference. When I soot something with that rig it is always on a tripod and always stopped down..and when I see the real world results there is just no complaint from me! Thanks for the feedback...I am going to check out that comparison to the 16-35 II zoom on TDP!

I read a review BEFORE I bought my lens (I just looked for 20min and cannot find the review...but I did read it) and there were sample photos showing less color fringing with the 17mm TSE II with 1.4X compared to the 24mm TSE.

I suspect the review was comparing the TS-E 17mm to the original (MkI) version of the TS-E 24mm, which didn't have the stellar IQ for which the MkII version is known. 

But I'll reiterate what I stated initially in this thread - the only meaningful differentiator between the TS-E 17/4L and the TS-E 24/3.5L II is that one is 17mm and the other is 24mm.  In practical use, the IQ differences are insignificant.  Regarding using a 1.4x TC, the greater tilt capability of the 24 vs the 17+1.4x might be of significance in some applications.  Also, tilt has a pretty deleterious effect on IQ - I wonder how the tilted 24 II compares to the tilted 17+1.4x.

You may be correct...It might have been comparing the 17mm II combo TO THE OLD 24mm and I was unaware of it.
Again...I have to say...the results that I achieve with the 17mm TS-E + 1.4X are very, very good..especially if I stop down to f/8 or f/11. 
This stuff is complicated and tedious!!!

Lenses / Re: Which TS lens is better

Better?  If you're referring to the original TS-E 24L, maybe - but the TS-E 24L II is sharper than the bare TS-E 17mm, and decidedly sharper than the 17 + 1.4x (very obvious in the TDP crop comparison).
In a head to head ISO chart comparison, the TS-E 24mm f3.5L II is the sharper lens. It beats almost anything you can compare it to. And it combines incredible sharpness with all the other qualities that one could wish for.

But the 17mm is also an incredible lens and with our current sensors, I believe the differences between the two are a bit academic. I am a bit worried though, walking around with the unprotected bulging front lens.  The image below is a shot, unedited raw to jpeg in LR, except for size reduction to fit the 4M size limit, with the 17mm on 5DIII (1/50s, f5.0 and ISO100).
In the Digital Picture comparisons...yes if you are pixel peeping and both the 17mm II with 1.4x vs 24mm II TSE's there is a slight difference (according to this comparison)...but even here..if you stop both lenses down a stop or two...you can really see no difference....it is negligible.
For me ...working on a tripod...I can just stop the lens down...I never shoot with it wide open..never. (I guess maybe astro photographers would a lot, though).  Someone else may have different needs...but putting on a converter and stopping down a stop or two and that save me $2500 while still giving incredible results and lightening the load in my bag....Can't beat it!
Conversely ...if you are going to mainly shoot with the 24mm...then I would say to buy that and be done with it...
but I reach for the 17mm first...so this really works for my needs...   Again... in the real world, the results are so good that if you have a good shot..no one will ever notice the difference unless you are making a huge print and peeping very heavily. I dare say the results will blow away anything that my 16-35mm II would have set on 24mm.
