Is the nikon z dx mc 35mm f 1 7 sharp wide open?
I don't have sharpness test results for the Nikon Z DX MC 35mm f/1.7, so I can't tell you how crisp it is at f/1.7. What I can tell you is that f/1.7 is a wide opening, and wide openings are where lenses are usually judged hardest. Stopping down a little, to around f/2.8 or f/4, is the safe move if you need edge-to-edge detail.
The lens itself is a small APS-C prime that also focuses close, to 0.67x. It fits a long list of Nikon Z bodies, including the Z50 and Z30 natively.
For what f/1.7 does to your pictures, the lenses guide explains aperture and light, and the portraits guide covers how wide apertures affect background blur.
