Is the yongnuo yn50mm f 1 8 df dsm sharp wide open?

I haven't tested this lens for sharpness, so I can't tell you how it performs wide open. The Yongnuo YN50mm f/1.8 DF DSM page covers the basics: full frame use on Sony E and Nikon Z, autofocus, no stabilisation, and how it frames on APS-C.

For what f/1.8 does to your pictures, the lenses guide explains aperture and light, and the portraits guide shows how wide apertures affect focus and background blur. If you want real-world sharpness results, look for an independent review that tests this lens at f/1.8.
