Reviews / Re: Review - Sigma 24-105mm f/4 DG OS

Ugg. Focus shift.
Yeah, there's a term for that right? "Non-parfocal" but neither is the Canon... for what that's worth.

No, they are two different things. 

Parfocal means a lens maintains focus while being zoomed, it's a very useful feature for shooting video (whereas with stills, it's generally easy to refocus after zooming).  The Canon 24-105L is not parfocal (the 17-40, 16-35, and 70-200/2.8 non-IS are parfocal).  Not sure on the Sigma, but I'd guess it's not parfocal.

Focus shift means the focus changes when the lens is stopped down.  No problem shooting wide open, but if you stop the lens down to f/5.6 or f/8 with a close subject, that subject will likely not be in crisp focus with the Sigma 24-105.  With more distant subjects, the effect is masked by the deeper DoF.  The 50/1.2L is notorious for focus shift (people call it a 'backfocus problem' usually because of a lack of understanding the real issue).

I experienced some Sigma focus shift today in fact. I was a bit perplexed when I was using LV to manually focus the 50mm at f/4, and when I took the shot it was slightly off. The 24-105L didn't have this issue. Is this due to the fact that when focusing the aperture is wide open at f/1.4 on the Siggy and f/4 on the Canon? That is kinda useless then if using LV. Makes AF accuracy even more important.

For me the lens is just too heavy. I'm sure it would make an ideal lens for a lot of people though its just not really a travel lens, is it?

I also don't like the way it zooms, it looks weird.

I've only had my 24-105L for less than a year but it's already my most used lens. Yeah it has it's faults but damn that thing is just so useful. Kudos to Sigma for making a cracking lens though.

OK, I got the Sigma 50mm 1.4 non Art version today and had a short muck around with it. After a +7 AFMA it seems to be behaving a bit better and though not as accurate as I would like for the larger apertures, the hit rate seems to be much better than before. At MFD or close it is really badly front focusing at like +15. Might run it through Focal when I have more time.

Overall IQ is actually pretty good even at f/1.4 with plenty of detail. A bit more CA and fringing than the 24-105L at f/4 but nothing too distracting. Not bad for the price, might hang on to this until the new Sigma and Canon 50s come out and then go head to head.

A sample at f/1.4 with only the Lens Correction Profile applied ...

I gave up waiting. Going to try the old Sigma 50 1.4 for now and see how it goes. Might upgrade to the new one later this year after the price settles and there are a stack of good reviews.

i'm also getting impatient, but will continue to wait for the soggy 50 art.  i've read to many negative reviews on the original sig 50 1.4...I'd stick with the canon 50 1.4 IMO

I had the 50mm 1.8 II for a while and it was OK for the price. The Canon 50 1.4 seemed like the logical choice but from what I can tell there are some issues with it that concern me such as the AF motor and it's durability. Then I also compared f1.4 from Sigma and Canon using TDP image comparison tool and the Sigma looked nicer. Bokeh is also reportedly nicer on the Sigma. Plus the Sigma is a newer design compared to the ancient Canon version. I'm not going to buy anymore ancient non L lenses - the 85 1.8 was a disappointment.

Finally the Sigma worked out slightly cheaper and takes 77mm filters that I already own.

I can live with a little wonky AF as long as overall IQ is good from f1.4 to around f/2.8.

I'm kinda in the same boat.  I think I want to buy the old sigma 50 for $275... but I'm concerned that it's auto focus is going to be whack... and then someone else will buy it and not be happy with it.

I ordered a used one. If the AF is out of whack even after AFMA I'll just use LV and manual focus it. Most of the time I shoot static stuff anyway. No biggie. For portraits I like to shoot slightly stopped down. I just like the 50 look and the only thing I have is the 24-105, which isn't all that great. Hoping for some cheap bokeh thrills really! Haha!

And second place is still second place, as in there is another camera that is more popular.

Firstly, there are more than 30 models of mirrorless cameras out there and to be ranked in second place is nothing to snort at.

Secondly, the most popular model, NEX-5R, only managed to capture 11.9% market shares, a smidge more than the EOS-M at 9.2%. If the most popular model is commanding 20 to 30% market share, then you may have a point here. But that's clearly not the case here.

Still hardly ever see them out in the wild. No one I know owns one.

You could have been a bit more tactful with your put down. I hardly stated any numbers or facts to begin with, and yeah I should have researched it and added that it was my opinion that it seems a less popular option.

To extend your personal observations based on a small circle of people you know to the entire population of camera users in Japan is to spread falsehood with no basis.

What exactly are we trying to achieve here?

As you can see I have an EOS M. I Like the EOS M. I want to see more lenses for the EOS M. I wish the camera had more notoriety and market share so that Canon might create more for the EOS M.

Which part do you disagree upon?

No one listens to my observations or opinions anyway. Sorry if I have tainted the web with my deceit!

Lenses / Re: Where do you sell used lenses
« on: February 14, 2014, 01:19:02 AM »
I have only sold one lens, but I'll add my experience here.

Not long ago I sold an EF 75-300mm f/4-5.6 III (non-USM).  It is one of Canon's most-maligned lenses, so I wasn't sure how easy it would be to sell.  I got the lens as part of a package when I was a newbie to DSLR photography.

Tried selling it for $100 on Craigslist.  No bites.  Waited a few weeks, tried selling it again for $80 on Craigslist.  Nobody was interested again.  I saw I could get $60 for it from B&H, so that would be my last resort.  I tried selling on eBay for $100, and it didn't sell.  I tried the $80 price point again, and I ended up selling for $82 plus a $10 shipping fee on eBay.  It was the first time in many years since I had sold on eBay, and stupid me, I forgot to check the fees before listing the lens.  They were much higher than I remembered.  So I grossed $92.  PayPal's cut was $2.97.  eBay charged a final value fee of $8.20 and a final value fee on shipping of $1.00.  The shipping cost me $12.41.  In the end, I only netted $67.42.  There's no getting around shipping, so let's concentrate on the eBay/PayPal fees.  They ended up taking nearly $11.17, or 14% away from my sale.

I have an EF-S 18-135mm lens I want to sell now.  Not sure if I am willing to lose a significant portion of my sale to eBay/PayPal again.  Those stories about sellers getting scammed by eBay Buyer Protection are scaring me.

I find amazon marketplace fees to be moderate, certainly lower than 14%! Ouch!

The EOS M isn't that popular in Japan either, but at $300 it is at least affordable.

That is entirely FALSE.

After its price cut, the EOS-M is the SECOND most popular mirrorless camera in Japan in 2013 (see http://bcnranking.jp/news/1312/131227_27056.html) and this enabled Canon to capture 9.3% of the mirrorless camera market share (see http://bcnranking.jp/news/1401/140110_27101.html). In contrast, Panasonic and Nikon with their MULTIPLE camera models only managed to capture 14.2 and 9.2% market shares.

Please get your facts straight before you post rubbish on the web.

Fair enough, I stand corrected. 9.2% of the Mirrorless market is hardly anything to have a song and dance about. And second place is still second place, as in there is another camera that is more popular.

Still hardly ever see them out in the wild. No one I know owns one.

Well....I NEVER thought that I would say THIS....but I am more interested in What's Next From Sigma!!!   :o

+1.

Tamron too. They're doing much more interesting things, these days, especially when it comes to value for money!

Now if Sigma came out with a Foveon DSLR of similar resolution to the 5D Mark II/III and the new lenses could all be bought for it... mmm...

And Samyang too! I'm looking fwd to seeing what they do with AF if rumors are true.

Sad days when a we get more excited about 3rd party gear more than Canon.

Sounds like the rumors about the 7D II release are finally solidifying. That's good news, about time that camera was finally released.

It is also very interesting to hear the 100-400 might finally be getting it's replacement! I'd be fairly interested in that lens.

I totally agree about the G1X II price...very odd. I think whoever is managing the G line and the EOS-M lines are really not in tune with the western markets. The positioning of those models is too high up the price ladder for over here. They may sell like hotcakes in Japan, but Japan isn't the US or EU.

Canon needs to bring a full mirrorless ecosystem to the US. An -M with a couple basic lenses will never break through the established DSLR market. Too many people have Rebels, and too many have purchased additional lenses. EOS-M needs LENSES! Would be really nice to see something like EOS-M Pro released here in the US with a whole range of lenses from maybe a fisheye prime, through wide primes and zooms, to long primes, to long zooms and maybe a telephoto. That's a big handful of lenses, but I don't think the US market would be interested in EOS-M unless there are some good, dedicated lenses for it at the same time. (And an EVF, of course...I guess that one is a given.)

I agree the G1X at around $400 is an attractive second camera but the mark 2 is ¥81,000 on amazon.jp, that's $90 away from a brand new 7D! You'd have to be mad!

The EOS M isn't that popular in Japan either, but at $300 it is at least affordable. The M2 is overpriced too and selling poorly with bad reviews on amazon.jp. I don't think Japanese people want to spend over $500 for what are perceived as "digicameras" or compact cameras. Almost everyone here has an iPhone or a smartphone and I see a lot of people using them or DSLRs when it comes to events and things like cherry blossom season.

I would like to see more lenses for the M mount. And I want Canon to take mirrorless seriously and make a decent M3 worthy of forking out five hundred bucks. The M2 is a joke. Improved AF and wifi for double the price? No. They should have been in the original M to begin with.

Thought I'd post what I ended up getting, after considering all the fine advice:

RRS BH-40, with lever release and panning clamp, an RSS L plate, and for the tripod legs I decided to go with carbon fiber, but compromised on the price, since I got the expensive ball head, and went with Manfrotto 055CXPRO3 instead of Gitzo or RSS.

Even though my heaviest lens is only a 24-105mm, I thought I'd go with the BH-40 in case I get heavier lenses in the future and because I wanted the independent drag on the ball head. I went with the panning clamp so I didn't have to worry about leveling the legs first when shooting panoramas. The only thing I didn't get was the nodal slide, but I can always pick that up in the future.

Are you happy with your choices a few months out? Thinking about tripods myself and trying to learn from your research :-)

I recently bought the same combo and it's been amazing so far. The tripod isn't as light as I thought it would be but the extra heft adds some stability.

The Manfrotto carbon fiber tripods are considerably heavier than their Gitzo counterparts.
@Badger: If you are going carbon fiber, I'd definitely recommend Gitzo. It's light and still very sturdy (I got the GT2541). An expensive tripod that I can carry beats a cheap tripod staying home, any day. The RRS ones don't collapse as compactly (not talking about travel tripods).

I was initially gonna buy the GT2531 but when I played about with it in a camera store one of the legs came off in my hand and I couldn't get it back on. Left me with a unfavorable impression (sure it was my fault but still I took it as an omen!). The metal manfrotto was good to me in the past and I was already used to the layout. And the $200 saved also helped my decision!  ;)

I don't use a tripod that often so even that combo I bought was hard to justify.

Anyway, I'm more than happy with it.

If I ever do upgrade it'll be to an all RRS setup.

Especially because I bet the photogs get pretty far from wireless access points at times....

Well, I'd think they would have the place covered, especially since all current professional cameras are WiFi enabled.

What "pro" does Canon have that's WiFi enabled.  The closest you can get is a 6D, which is not really something I would be using for sports.  None of the 1-series or even 5-series have WiFi.

I think he meant the Wireless File Transmitter?

Canon General / Re: So much redundancy...
« on: February 11, 2014, 08:15:00 AM »
There's something about a lens in your collection that never gets used and is, as you say redundant, that gnaws away at the back of your brain. The 85mm 1.8 was like that for me.

I feel like I have just the right amount of overlap between the zooms now with just a few choice primes at carefully chosen focal lengths. Finding those focal lengths was (is) a bit of a mission though!

Having the 135L I often wonder if I would also benefit from the 100L or if I should swap. Focal length wise the look is kinda similar and potentially the 100L could kill two birds with one lens. Portraits and macro. But there's just something about 135mm @ f/2 that is soooo creamy and bokehlicious that you just can't give it up!

Keep them both I say.

I agree with all of the above.  Don't waste time with cheap stuff.  A tripod needs to hold up over time, be transportable, and most important, keep the camera stable during the shoot.

There are different ways to extend the legs (latches, rings and the like).  Next you have 3 or 4 segments, with more segments usually less stable, but smaller when collapsed.  You need to consider how tall you are and how tall you need the tripod to be.  Really Right Stuff web site has a nice chart on its front page you can look at for this.  No center column greatly enhances stability, and decreases the weight of this element.

Some tripods have a hook to hang additional weight to stabilize the unit- helpful during windy conditions.  Some either come with, or have optional "accessories" that you may later purchase.  These may not be important now, but keep an eye toward the future- like the leveling plate as mentioned by Neuro-  it may not make sense to you now, but as you expand, the ability to use these items may become essential.

I totally agree that your head should be a separate purchase.  This is a personal decision as the tripod legs.  A lot of things go into this decision.  One very important thing is the plate- Arca Swiss is my vote.  Another thing is the layout of the tightening knobs.  Be sure that they work for you, and be sure the head will carry the camera/lens load.  Play around with it for a while to be sure you like it.  I have a collection that look pretty but I hate.

I have a Manfrotto 190CXPro3 and it is a great tripod.  I am going to get a RRS TVC-33 when I get my big white lens

So, be sure that the combo is easy to carry, easy to set up, and stable.

Cheers

Scott

I have a stupid question, I have a Manfrotto 055CX3 and it came with a hook attachment; however, I'll be damned if I can figure out how/where this hook attaches to.

Not quite sure what you mean. Can you take a picture of the attachment and also one of the tripd base and center column?
