100% crop wide open, canon 7d. no autofocus issues, sharp as a tack. great fast prime that stacks up nicely to the canon L series for a fraction of the price

Nice.

Left eye looks a little noisy, what was your iso?

...that doesn't look that sharp to me...maybe not the lens though? looks like a low-light area. Like the other poster said, what ISO was that shot at?

800 i believe, although it was set to auto iso.

it isn't "l" glass, but compared to some of the horror stories i had heard, i was quite pleased. the 7d isn't known for being razor sharp out of the camera. i haven't post sharpened this; after that it should be pretty good

i was close to the subject at 1.4 as well, the DOF is pretty damn thin, so not everything is perfectly in focus

for a 100% crop thats noisy? i have to get used to the standards the photography industry has. maybe in 10 years i'll be able to get afford some the real deal canon primes...

Firefox has an exif viewer add-on, I just right click on a photo and select exif data.

If you use DPP, you can right click on your pic and select info (or cntrl+I).

I think that looks pretty good for 1:1 crop. After all, it is 18MP.

If anything, it's just showing a little chromatic aberration.

I was thinking about the Sigma 30mm f/1.4 back when I got my first Canon dSLR (XTi). I opted for the Canon EF 28mm f/1.8 instead. That was a fine lens. I sold it though when I bought the Canon EF 35mm f/1.4L. The 35L is nice on APS-C, but even more fun on full frame.
