B&H is going to send me both the 50 Art along with the older Sigma 50 so I can compare them side by side.  I don't own the Sigma dock, and so I am wondering how much of a factor that is going to be to getting accurate AF from the newer lens.

Do I need to have them send me the dock, too?

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 should

Yes. That simple, mine would have been useless without it.

The lens just arrived from B&H. I currently have the lens my set at +12 on my 5Dmkiii. When the focus hits, I have never seen a lens so sharp. The color and contrast are soooo good. Here is a SOOC shot of my wife @1.4.

What is the hit rate % on your copy? The photo looks really good.

Thanks

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.

Feeling sick, so stayed inside and someone is pretty bored by the looks of it. Btw, it's the same look I have before morning coffee.  :D

Nothing much, but for someone wanting to see 1.4 performance I thought I drop it out there.

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.
