Is the nikon z 40mm f 2 sharp wide open?

I don't have test results on how sharp the Nikon Z 40mm f/2 is at f/2, so I can't say for certain. What I can tell you is that it's a small, cheap, everyday prime with autofocus, made for full frame, and it works on APS-C Nikon Z bodies too. Full details are on its Nikon Z 40mm f/2 page.

On the shooting side, f/2 is a fairly wide setting, so depth of field is thin. The Lenses guide explains what the f-number does to light and background blur. If you shoot people wide open, the portraits guide covers why eye autofocus matters so much at that aperture.
