Is the canon ef 28mm f 1 8 usm sharp wide open?

I don't have sharpness test results for the Canon EF 28mm f/1.8 USM, so I can't tell you how crisp it is at f/1.8. What the page does cover is the lens itself: a 28mm prime for full frame, with autofocus, no stabilisation, and f/1.8 for shallow depth of field and low light.

For what wide apertures do to your pictures, the Lenses guide explains the f-number, and the Portraits guide covers how thin focus can get. If you tell me what you plan to shoot, I can point you to the right kit.
