My copy of the 50 Art works well with regular AFMA, but some, like Viggo, apparently needed the dock to adjust pr. FL. If you can have it, you probably shouldTWI by Dustin Abbott said:

UPDATE
The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being. I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure. ------------------------------------------------------------

I haven't gotten a chances to really test it out now, but it is definitely over 90%. It hasn't missed a shot yet tonight, and I was being pretty tough on it. I have two sessions this weekend, so I will know more after those, but even if I had to manually focus with live view, the lens would more than worth $950.

Great shots! Really like the last on there.
I have figured out the AF finally. It's absolutely flawless when the contrast is great, really really impressive! BUT in indoor light in the middle of the day I get almost nothing sharp.. I saw yesterday when shooting my daughter and a few rays if light in the window, whenever she had no direct sun I got nothing at all, but as soon as she had a little light/contrast on her it locked perfect. I saw the same outside, shot some houses far away and when they were in the shadows, but my no means dark and low contrast, it would front focus with several hundred yards, but if the same distance houses had more light in them, perfect every time.
So the great news is that focusing is not unstable and all over at all, in fact it's better than most L-primes I have owned. On a tripod and high contrast target it just can't fail.
The really bad news is that shooting with normal to low contrast it's really poor, so bad I took 23 shots in a row switching between Servo and One shot, I couldn't get ONE shot sharp of my daughter just standing in front of me.

That's too bad. Have you thought about exchanging it? I have done that with Canon 50's before. My Sigma 50 is spot on indoors in low light even when focusing across the room. It is also spot on outside in backlit and high contrast situations.
The bad thing about returning it for you is there might be stock for a while...

Stock is not a problem here, but exchange it, I can't really see the lens being faulty when it's completely epic in good contrast light. And it's basically my daughters face and sometimes my sons that is the really hard part, somehow I doubt that can be fixed with another copy.

I took the lens on a trip to Amsterdam this weekend. Cold, wet and windy, so I had lots of opportunities to shoot uninteresting images in poor light. I am convinced about the sharpness of this lens. In general I also find the bokeh very satisfying. As long as you avoid very contrasty elements, like light through leaves, reflections from water with ripples etc. I am very happy with it.
My main concern with the lens is its AF. I, as some of you have seen, have been very skeptical, due to my experiences with the 35 Art. But this 50mm has been quite impressive so far. The attached image is (since weather dictated a significant number of bar visits ...) a 1/100s, f1.4, ISO3200 from the 5DIII. I have lifted the shadows a bit and lowered the highlights. A single AF point was on the bar maids ear.

Nice to see Eldar! I'm currently feeling the 50 Art as my favorite lens EVER. I can get better IQ and AF with the 200, but I have always had a thing for a 50mm? But never got the IQ I wanted with the double gauss design. Now that the 50 art is not only great, but the best performer I've tried except for the super tele it's bolted to my camera. Loving it, and after docking calibration, I'm very happy with the AF, except for tracking sometimes, which I think is due to bug in the firmware with AF stopping if the shutter is half pressed every now and then.
Btw, that bar, it looks like one I visited next to "Club Smokey" on the Rembrandts Square or something, lol.

COOL! I can't wait to read your comparison!
I own the original 50mm (and I have an Art 35mm and just bought a dock for it and potentially to use with a 50mm Art as well.)
I am on the fence about the 50mm Art. Really like my original 50mm Sigma. I know that the new lens will be sharper, more contrast etc...just way better in most respects...yet the original is way smaller, and has a great rendering more like the 50mmL in many respects. I even have a friend dying to buy my old Sigma...so it is tempting to step up to the new ART.....
Yesterday, I downloaded the software for the Sigma Dock and updated the firmware on my 35mm Art...which was already one of my favorite lenses...Pretty cool tech there. I plan on learning the software soon and understanding how it adjusts the focus..but to tell you the truth, I have no complaints with that lens.
Get the Dock, Dustin and do a full uber review on the whole shebang...I think everyone will enjoy that!

Upgraded from the original Simga 50 to the Art 50…. Have a much higher hit percentage on the autofocus, and the image is just very sweet… I would recommend upgrading (the size isn't that much more in reality, unless it just won't fit in your camera bag).
