Is the olympus m zuiko 75mm f 1 8 sharp wide open?

I don't have test results on how sharp the Olympus M.Zuiko 75mm f/1.8 is wide open, so I can't say for certain. The lens page covers what I do know: it's a Micro Four Thirds prime with autofocus, no stabilisation, and it frames like about 150mm on full frame.

At f/1.8 the depth of field is very thin, so a small focus error can look like softness even on a sharp lens. The aperture guide explains what the f-number does, and the portraits page shows how to use that thin focus. For sharpness figures from other sources, check reviews that test this lens directly.
