Are Sigma Art lenses often good-to-go on something like a 6D without any adjustment?
Thanks.

Cory, I have own(ed) more than 20 Sigma Art and Sport lenses in total, and helped many other photographers in getting their Sigma Art and Sport lenses AFMAed right, I can attest that there is not a single chance in the world that any given Sigma Art or Sport lens may be absolutely "spot on" out of the box on Canon 6D unless you shoot in live View mode exclusively, be prepared to invest some time in AFMA calibration. You do need the Sigma USB dock to achieve a solid result though.

There is no possibility that you own 20 art lenses and none worked out of the box! I have 24, 35 and 50 art. All.kf them work without any afma on both my 6d and 5d3. I had issues with my first copy of 35 art. Returned that and 2nd copy works fine.

Please stop spreading false claims.

I believe you misunderstood SecureGSM comments. Here is how I read his comment.

He is saying that passed upon his experience of 20 Sigma lenses, there is no guarantee than any one lens will not require some AFMA adjustment. Some may be spot on, others may require a bit of adjustment.

Re: Sigma 24-70mm f/2.8 OS Art Pricing & Availability to be Announced Shortly

It's all good. I take from that that it may be OK and it might not.
With that, I may order this potentially remarkable lens and then immediately return it if not.

Re: Sigma 24-70mm f/2.8 OS Art Pricing & Availability to be Announced Shortly

. here we go. Firstly, I know what I am talking about. I have seen quite a few that were spot on out of the box at x50 focal length but never spot on at MFD, Infinity, x50 and in between. does not exist. period... The largest deviation from the norm with Sigma Art and Sports lenses I have ecountered so far are at MFD and at Infinity. I presently own the following Sigma Art and Sports Lenses:

24 Art, 35 Art, 50 Art, 85 Art, 135 Art, 120-300 Sports lenses
There is nothing that good AFMA can't fix though.

How would you compare the sigma usb-dock, vs the usual AFMF from the camera?
Is it better more reliable?

Re: Sigma 24-70mm f/2.8 OS Art Pricing & Availability to be Announced Shortly

great question. thank you. traditional in camera calibration of a prime lens conducted at around x50 focal length of the lens. Your Canon or Tamron lenses usually can be calibrated in camera. With Sigma Art and Sports lenses I found that a single point, in camera calibration at x50 focal length of the lens is not enough to ensure that you are going to get the best AF performance at MFD and at infinity.
I found that Sigma Art and Sport prime lenses need to be calibrated at 4 distances to the target otherwise you going to get a substantial deviation from best AF results if you shoot at MFD or infinity unless you shoot with UWA prime where DoF is quite forgiving. Sigma USB dock provides 4 caibration points for primes and 16 calibration points for zoom lenses. It can be very time consuming with longer zooms but worth it.

Re: Sigma 24-70mm f/2.8 OS Art Pricing & Availability to be Announced Shortly

A percentage of all manufacturers' lenses and all manufacturers' cameras when combined can have unsatifactory autofocus "out of the box". Cameras (lens mounts) and lenses are made to very tight tolerances, but there is still a small range of "acceptable" dimensions achieved in mass manufacturing. If your specific camera is right in the middle of size variance and your specific lens is right in the middle of intended size variance for that camera system mount, then things will work "out of the box". If you have a camera and lens pair that are at the same end of the allowable range (both short or both long), you will need to make a microadjustment to your AF system.

My 6D gets on just fine with the AF on my Sigma Art 35mm f/1.4.

Re: Sigma 24-70mm f/2.8 OS Art Pricing & Availability to be Announced Shortly

AFMA is an interesting topic. Personally I have never tried to do it and have never found a need for it. I do have some large aperture lenses where I would think I would notice if autofocus was off (Canon 70-200 f2.8 and Sigma 85 f1.4). As I said I have never tried it so perhaps if I knew how and I put them on a test chart I might find that I needed some adjustment on at least some lenses. However in real life use all of my lenses appear to focus fine with no adjustment. So either I am not that picky or those who do AFMA are paranoid. I suspect the truth lies somewhere in the middle.

Same here - I've never used it either. When i get a new lens I tend to test it by focussing on something really close at the widest aperture & if it seems sharp at 100% I consider it to be OK. But perhaps I'm missing out?

For those who do use AFMA, do you test each new lens routinely or only if you suspect the focus is out?

It's always seemed a bit too long winded a process too but perhaps i should invest in Reikan FoCal although their site seemed to suggest there were some issues using it with the EOS 6D.

However with regard to SecureGSM's comments, is it because Sigma has poor QC or that they need AFMA more for some other reason?

First off, I'm really really excited to see this lens come out!! I have no doubt that sigma will compete with canon's offerings without much problem.

talking about AFMA though, I've had to AFMA a few of my lenses - they were the canon ones too. Especially the ones that I use primarily for portraits. When you need the sharpest of the sharpest focus at the eyes, man, AFMA can make or break your shoot. It's just a pain that you have to AFMA it at the close and long end. I'm still a novice at it but it is a very very useful tool that I appreciate.

Re: Sigma 24-70mm f/2.8 OS Art Pricing & Availability to be Announced Shortly

I'm also pretty excited about this lens. Have the EF 24-70L 2.8 and was hoping the II would have IS, then I would have spent my money on it. Without, I couldn't justify spending that much. My hope is that the Sigma is better than the one I have and also around or below $1,400. We shall see.

As to AFMA, I have used it on prior cameras and agree that with the single adjustment, it didn't seem to make much sense on most lenses. I did dial it in for my EF 85mm 1.8 at the typical portrait distance I shoot at. However, when I got the 5DIV, I don't seem to need any adjustment (at least noticeable to me) for any of my lenses.

Ditto. And I spend most my time at f/1.4. Maybe we're just lucky.

Among my current lenses, I had to AFMA my 100mm f/2.8L macro and the tele end of my 70-200 f/2.8L. But many of my lenses have been pretty spot on right out of the box. Most my lenses are newer (manufactured in the past few years) and I have this working theory that the tolerances have gotten better and better.

Why a Sigma with no IS when Canon is about to release one with IS

OS in the name of the lens stands for Optical Stabiliser.

I have two issues that have held me back from the Sigma Arts, so I'm keen to hear your take on them.

1. I had a 35mm ART on my Canon 6D. I did find the occasional complete AF miss (i.e., not just a small miss, in that AFMA would fix this, and not a miss because the AF point accidentally fell on something other than the intended subject). Have you experienced much of this with the lenses that you have and, if so, have you experienced it more with the "older" ones (i.e., 50mm and 35mm)? That is, should I be less concerned about this with the more recent 85mm and 135mm?

2. I shoot RAW + JPEG (for a few reasons, but often because I want to get images out of the camera on the spot and send them to the person in the image, e.g., shots of my extended families when we get together). I know this annoys some people, but it's what works for me. When I changed from a 6D to a 5Ds, there was an incompatibility with the Sigma 35mm Art, in that the JPEGs showed "rings" in the images. Turned out that this was because I had certain corrections turned on, although when I sent the images to the Sigma reps here in Australia, they had no idea what the cause was. I'd prefer to leave this setting on for when I shoot with Canon glass, and I don't want to think about diving into menus to change settings like this each time I change lenses. Do you know if this has been resolved with a firmware update for the older Art lenses? Obviously this is a limitation of buying third party glass.

Essentially, I want to get a fast 50mm lens, and none of the Canon offerings seem worthwhile. I'm waiting just like everyone else for a new release! In the meantime, I'm considering the Sigma 50mm, but given my issues with the 35mm, I'm hesitant. Your thoughts would be appreciated - thanks in advance.
