Gave it its first serious use today... and I left myself more confused than when I started. Long story short, initial testing seemed to show focus was good enough, so I just used it. I saw backfocusing in the field but wasn't sure if that just me being too rusty on using the 5D2 or was it due to the lens. Then I noticed the AFMA was set to +17. My guess is this is the value I entered for the Zeiss 50 makro, and as they report themselves as "50mm lens" they ended up sharing the same value. I tried fiddling with it in the field but was getting nowhere.

Now, the above didn't stop me getting shots, although it may be a question of focus reliability. 50mm f/1.4 at close range for wildlife wasn't the best mix, as the DoF was often smaller than the width of the subject's eye...

Swan vs. dog by Crestie Crazy, on Flickr

Canon 5D mk2, Sigma 50mm f/1.4 A, at f/1.4, 1/5000s, ISO100.

A quick sample for now. This was more distant, and the focus was good enough by luck I have to admit. I did crop this image to better frame it, but if you can figure out flickr's current interface it is 100%. I should also add I just did a quick and dirty process on this, and the 100% view wasn't optimised as it was just an intermediate step to a smaller web view I posted elsewhere.

I need to get bigger ND filters as even on this overcast day I was close to overexposure when wide open.

Hey all, so I just got the 50 art not long ago. I used it for my recent family shoot and noticed it was hitting about 85% of the time it probably needs a minor adjustment.But when it hits the shot stopped down oh is it ever pretty blows my 50 L in terms of sharpness and in my opinion the bokeh is pretty spectacular. The 85L is still my favourite but this this lens is right there.

Snapshot from when we got home from kindergarten today, @1.4



From this afternoon at the playground, I pushed the swing and quickly pulled up my camera and took one shot before I had to get out of the way, needless to say, the 50 Art focusing issues are very much gone. Shot at 1.4.

Great to hear that Viggo... oh, and great shots too.

Thanks! I love this lens more and more each day. I'm buying a second copy 35 Art over the weekend, hopefully the AF doesn't suck like the first 35 and the first 50  ;D At least now I have the docking and I know that they can work and be epic.

I don't think you will regret the 35 it's AF in servo is amazing and my copy just never misses focus i cant wait to see what they do with the 85! it needs some wide open improvements and AF could be made better over the current version

I sold the 35 in one day, it was just more of the same rubbish, I will never buy it again, ever. The 50 however is basically all I use now, I think it's one of the greatest ever.

I gave up on both the 35 and 50 Art lenses. The 50 is sold and the 35 will go as soon as I get a reasonable bid. With the AF issues I have had with both, it will be a loooong time before I buy a Sigma again ... A pity though, considering the excellent optical performance of both lenses.
