Is the nikon af s 28mm f 1 4e ed sharp wide open?

I don't have sharpness test results for the Nikon AF-S 28mm f/1.4E ED, so I can't tell you how it performs wide open. What I can tell you is that it's a fast prime for Nikon F full frame bodies, and on APS-C it frames like a 42mm lens.

Shooting at f/1.4 gives you the most light and the thinnest focus zone. The aperture guide explains what that means for exposure and blur. If you're shooting people, the portraits page notes that at f/1.4 the sharp zone can be thinner than a face, so stopping down to f/2.8 is often the safer choice for groups.
