Is the olympus m zuiko 12mm f 2 sharp wide open?

I don't have sharpness test results for the Olympus M.Zuiko 12mm f/2, so I can't tell you how it performs wide open. What the lens page does cover is that it's a small metal 24mm-equivalent prime for Micro Four Thirds, with autofocus but no stabilisation. You can see the full list of bodies it fits there: Olympus M.Zuiko 12mm f/2.

If you want to know what f/2 means for your pictures, the lenses guide explains how the f-number affects light and background blur. For a general sense of how wide-open shots behave, the portraits guide is a good read.
