I have used this lens during a prenup shoot. It's weird that if my subject is within 10feet this lens is tack sharp, but if it's more than that then it backfocuses. Not sure if this is a user issue.

Here are some sample photos.

Somehow, I am experiencing the same thing. I tried micro focus adjustment with my 7D but I can't quite get my grasp on it.

My copy has slight focusing problem too, but still i'm amazed with this magic lens

Here's my test shot the night after we bought it (no flash)..

Hi Alvin,
- for 19.8K @Henry's, does it come with SIGMA/JT warranty? (or just store warranty?)
- how much did it cost you to calibrate your lens by JT?
Thank you

Hi Mayk,

it also comes with JT Warranty & the store warranty..
I had my calibration from JT for free.. they just asked for the serial number to check on their inventory if they released that item to Henry's..
I also brought the receipt in JT just to make sure that the item is a legit on their side..

thanks bro!

cheers!

Have you guys experienced having trouble with autofocus or having inconsistent af when shooting people/subjects backlit?

Thank you Alvin, I've been pondering on getting this glass for a long while now, the only issue that is bothering me is the AF problem as some of the user here are experiencing, If that can be corrected by calibration then I'm getting one soon.

I had the same problem with my copy of this lens at a certain distance it is tack sharp, then when I move it back focuses. I also read somewhere that this is a common problem with the Sigma 50mm f1.4.

hello sigma 50mm 1.4 users, just want to get feedback from the people who experienced focusing issue? i'm planning to get this one.

I hope having crop sensor camera would not make me go to JT to have it calibrated always. hehe

Torn between this and canon counterpart.
