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.

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.

This is acceptable?? ???

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?

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).

Well, no, but it seems to not be that bad with other shots, and everything else is so perfect, I would rather live with the misses for those shots, than to go 50 steps back to the 50 L or something else.

Thanks, all, for these amazing samples you are posting.

I've been waiting one week now for shipping news from B&H...

In case anybody hasn't seen this extreme pixel peeping:

http://lcap.tistory.com/entry/Sigma-50mm-f14-dg-hsm-Art-Review

It's Korean, but the pics tell the story.  If the review mentions AF, I can't read it!

Sounds like AF either works great or not.  I imagine most members here have the latest firmware in their cameras...

The first shot is back focused, and only the last one is okay sharp to me at least. So it seems the tracking can't keep up.  I've got a few from indoors today that are really sharp, so I guess going back and forth with calibration is always a good thing.

The thing about the Sigma is that it is soo sharp that even slightly misfocused shots appear sharp enough.

How can you tell that it is back focused?  I can't see where his focus point was.  Is it in the exif data?  Sorry if this is obvious.

If you look at his face in the first shot, it's slightly blurred and the sand just behind him is sharper than underneath him. The focus is locked behind him, instead of his face.

First of all, it is a great series of shots that any father should be very happy with......

But to expand on what Viggo said, look at the blur on the wife over the three shots.  First shot she is almost in focus.  Granted it looks like the separation between the two increased, but part of that is back focusing on the first shot.  And I agree, looking at the sand, it is sharpest behind the subject.

Thanks for that.  I am interested as I have one of these lenses hopefully shipping hopefully soon. :D

But, Viggo, do we know if the running-boy shots were taken with AI Servo or One-shot?  Sometimes you can get a lock with one-shot, hesitate with shutter-release half way, take the shot, and miss focus...Right?

Hard to conclude from this set of three that AF on the Sigma is missing.  Do we know if on the second shot he attempted a little center-focus/recompose?

I have never seen anyone shoot a running person with one shot, that will never work when he's running that fast.
