No problem! Amazing how much info you can find once you track down the source of the issue! Exact situations with Canon lenses and the 7D, 5D2, rebels, etc... Not just third party lenses or the 5D3. I am finding many posts from years ago sharing the same behavior in artificial lights and changing planes of focus. Appears very warm light like halogen and compact fluorescent generally cause front focus while very cool light can cause back focus. Daylight is a blend of cool and warm so you will get most accurate MA values.

Completely fits to what I have experienced. Why some lenses experience more shift than others appears to be a result of coatings and transmission, I would assume. Solves my issue though so I am happy it is not my lens acting up. I will still note it when I send my body into Canon in case there is some type of adjustment they can do in the AF system somehow.

Very interesting information, thanks for looking into it!

well... we've seen reviews from all over the place on this lens, and many of us have hands-on experience with how awesome it is... this morning, I noticed that Roger from Lensrentals had put up his "Take" on the lens.

Roger's Take
Roger Cicala

President of LensRentals.com

It’s been a long time since a take was so easy. This is the sharpest 35mm made. It costs a lot less than the Canon 35 f/1.4mm or the Zeiss 35mm lenses. Any questions? It’s extremely well built and everything I’ve been able to see, inside and out, indicates quality control has really improved at Sigma.

If you’re a bokeh fanatic, you may like something else better (or maybe not, that’s a subjective call). If you need Image Stabilization, then the 35mm f/2 IS may be worthwhile. Otherwise, this is the 35mm lens.

Arguably as good or better than anything else made, and at a lower price.

Now... he's not saying anything too new, or anything in depth... but whenever I have a quick question on a lens, I normally take a second to see what Roger has to say about it... He's done another more in-depth review, but I think that the above statement really says it all.

Not allowed to repost images, but I got a few samples up from my trip (all taken with this lens) on the sample archive thread here:

I wonder how the mkII from canon will stack up against it. Can you please all go out & buy this lens & then sell it to me for 1/2 price when the Canon 35 1.4 L ii comes out?

I highly doubt the 35L II will be THAT much better. It may have faster AF and be sealed, but will it really be worth double the price? I find it hard to believe.

I have been somewhat anti-third party lenses until this one. It is THAT good. I find it hard pressed to tell it apart from any L lens I have used prior. Built better than a few, as well.

I don't think there is any question now that Canon's 35L II will need to be better than the new Sigma. It will likely cost 2x as much also but maybe they will add IS.

Never happen.... Look at what Canon has with IS. Nothing below f/2.8.... I wouldn't expect that to change anytime soon.... and if they somehow did manage to do it... I think more like 3X the price... rather than 2X.

oh yeah... forgot about that one.


My mind is flooded with all of the 2.8 primes hitting the market these days...

Did you experience this type of misfocus with your previous 35L?

I just had a newborn 11 weeks ago. I used my 5dmk2 with 35L with 100% full confidence using artificial available light in the operating room. 100% keeper rate in terms of sharpness and landing the shots. Not once did I feel a haunting mis focus issue.

It'd be interesting to see the results people are getting 6mth to a year down the road interms of AF accuracy. I'm eager to hear the results when all of the excitement diminishes.

I don't recall the 35L shifting as much, but I used it outdoors most of the time if I remember correctly and not indoors (or when it was indoors, it was natural light since it was summer). So I really can't give you an honest answer on that.

I can tell you honestly though, compared to the Sigma 30 I owned prior a few years ago... The Sigma 35 is like comparing the Canon 50 1.8 to an L lens in terms of build, focus accuracy, etc... I am not exaggerating one bit here.

Believe it or not, I tend to have worse luck with L lenses and needing factory service... For example my 24-70 II right now... Noticed a few scratches behind the front element last month and sent it into Canon via CPS Gold... I just got it back today after some 3-4 weeks while they ordered a new front lens group. The lens is flawless in that regard, but now it has a weird noise in the focus ring. They sent me a prepaid overnight label back for inspection, so I just dropped it off at Fedex again. In the past, I had my 70-200 II in the shop to get the IS assembly replaced. These are $2,000+ lenses that are having issues... It is not just Sigma or other manufacturers. Happens with everybody.

Damn near tempted selling my Canon 17-55 2.8 IS and try this baby out. I have a wedding to shoot this summer and the 35 1.4 might come in very handy?

well now that i've had a bit more time with this lens and shot both indoors and out and in different lighting conditions i can say i am happy with the consistency i am getting with the AF, MA of +9 is consistent outdoors as well as indoors with different kinds of lighting with various AF points on my 5D3
