I also bought mine at the beginning oh this year and Bridge doesn't recognise the right serial number. The first two digits are 10, which should mean that it was produced in October 2013 (at least this chart is true - http://www.the-digital-picture.com/Canon-Lenses/Canon-Lens-Aging.aspx)

Depending on how much stuff you want to carry in your backpack I would consider something like the f-stop ICU's (http://shop.fstopgear.com/us/products/icu.html) or Gura Gear modules (http://www.guragear.com/uinta/). These will not only protect your gear but also organize it well and enable you to load your rucksack with other stuff (jacket, food etc.) without mixing it with your photo gear. Works very well for me while skiing, mountaineering and hiking.

Quote from: Bryan @ TDP
Below I share ten 100% crops from one of the more-formal focus tests I performed. The subject is a large book properly aligned with the camera at a relatively close focus distance. Starting with a slightly defocused lens, each shot was autofocused using the center AF point that was very comfortably and completely covered by the book. The first 5 and last 5 images from this particular test are presented below and are representative of the larger test group. … The camera was a tripod-mounted EOS 5D Mark III with mirror lockup and the 2-sec self-timer in use.

Of those 10 shots, 4 are sufficiently OOF as to be unusable (3, 4, 6, 10).  A 60% hit rate with a static subject and a tripod-mounted camera, particularly one with an excellent AF system, does not inspire confidence. 


Also, this is a departure from the norm for Bryan's lens tests (and one, frankly, with which I'm not too pleased):

Quote from: Bryan @ TDP
My evaluation lens was a short term loan from Sigma, as they offered the production-grade lens before it was commercially available.

Any time a manufacturer supplies a product to a well-known reviewer, a big unanswered question is whether the provided copy is truly representative of units purchased retail.  Clearly, it would be in Sigma's best interest to pre-test a batch of them and pick the best copy they can find for review (in fact, they are supposed to generate measured MTFs for every lens they produce, so they have the data already).

I've always felt that one of the strengths of Bryan's reviews (in addition to their thoroughness and readability) is that he purchases review copies through standard retail channels (B&H may put him near the top of the preorder queue, but that's fine), and therefore avoids the potential confound of bias introduced by testing a 'hand-picked' lens from the manufacturer.  I hope Bryan chooses to test one or more copies of the lens purchased retail to see if the results align with the copy provided by Sigma.
I totally agree with your views. I was a bit surprised that Bryan published this as a full review and not just a preview. His objectivity takes a hit when he writes this based on a copy provided by Sigma. On the other hand, he still provides what appears to be a frank, open and honest review. I hope he goes back and provides a revision when he get copies through his regular retail channels. I also would have liked to see more image examples.

I have the 50 Art on preorder and I am looking forward to see what it is worth. But my experience with the 35 Art, where the AF perfomance is a bit unpredictable, is that I end up leaving the lens in the bag (if a 35/1.4L II came around, I would definitely try that). If the same thing happens with the 50 Art, and especially because my main reason for getting it is to use it from f1.4-2.8, I'll probablly reach for the Otus instead.

With US$10,000 I would get:

1D X
Spare battery
70-200 f/2.8 ii
Couple of 1066X cards
Good flash

I think that would come to around 10,000 if not then I would buy the 17-40 or 16-35 depending on how much I had left, if any.

This would have been a shut up and take my money moment until I saw that sync speed. :P
Why?  Light it with HMI's or LED's and roll with it. 

For HMI - That Arrimax isn't exactly portable, esp. not if you figure in its power supply. Or cheap, they cost much more then the leaf shutter capable alternatives. And thats if you need just one.
And LED? How exactly do you want to put ~200klx on your subject with those? Preferable from a reasonable distance. A superdino suddenly seems tame, and the few dollars for the LS turn out to be a bargain.

I was using sandisk card for the last four years and I didn't have any trouble with it. I advised you not to format on the PC, take it for the replacement. Once you formatted it, it stops working and gives you troubles all the time.

Great review, as usual. Now I'm considering cancelling my pre-order. Was hoping it would be as solid as my Sigma 35mm f1.4 Art lens, but if that's not the case, I'll stick with that and my other Canon L lenses.

Is there a lens out there that never has occasional AF inconsistency?

Does a 40% miss rate really constitute occasional inconsistency?  I think not...

Compare this to Zeiss missing 100% of AF shots  ;)

Well you could turn the AF off and then the Sigma lens would have the same rate of AF misses as the Zeiss lens, for $3000 less.

+1  ;D
