Is the panasonic lumix s 40mm f 2 sharp wide open?

I don't have sharpness test results for the Panasonic Lumix S 40mm f/2, so I can't say how crisp it is at f/2 without guessing. I'd rather not guess.

What I can tell you is that it's a small, light standard prime for full frame. It has autofocus but no stabilisation, and it fits the L-Mount bodies listed on its lens page. On full frame it frames as a true 40mm, and on APS-C it behaves like a 60mm.

For what f/2 does in practice, the lenses guide explains how aperture affects light and background blur. If you plan to shoot portraits wide open, the portraits guide covers keeping the eyes sharp when depth of field is thin.
