Canon EF 35mm f/2 lens review (tested on a 5D Mark III) by Ken Rockwell: This 35/2 is smaller, lighter and less expensive than any other fixed Canon 35mm AF lens. It's also just as sharp, with less flare, very slightly less distortion and better sunstars.

"This said, the Canon 35mm f/2 is among the sharpest wide lenses I've tested, just like the 35mm f/1.4 L (1998-) and new 35mm f/2 IS (2012-). The only differences between these and the 24-70/2.8 L II is if you're looking in the far corners on full-frame, in which case, this original 35/2 is slightly less sharp than the others wide-open, but the same stopped down, and the same throughout 95% of the rest of the image that matters.

This 35/2 is extraordinarily sharp and contrasty, even at f/2. Throughout 95% of the image, there is no difference between f/2 and stopped down, as seen on a 22MP 5D Mark III at the test range at infinity. As one stops down to f/8, the

last few percent of the corners of the image sharpen up, too — and when was the last time anyone even had anything in perfect focus in the corners so it would matter anyway?

So long as you're in focus, sharpness doesn't vary much from perfection, except by f/11, where diffraction softens the image.

Throughout most of the image (except the last millimeter in the corners), this lens is just as sharp at f/2 as it is stopped down!

Hey, sorry to spare you endless boring charts, but with a lens this good, there's nothing to show other than sharp pictures under all conditions.

The biggest detriment to sharpness will be a lack of proper vision and technique, never this lens. I bought mine directly from Adorama. I can't vouch for anything if you buy from a local store or chain where you never really know who's opened and played with your lens before you buy it. I never buy retail; too many risks, so why pay more?"
