I didn't shoot a lot with it yet but what i did on a tripod did look plenty sharp to me. On Pentax forums in the medium format thread on page 739 you can find some handheld shots from 'itshimitis' taken from a boat on a lake. They look terrific.
It is a heavy and big lens so I should hold it on the lens instead of your GFX body.
Here's another example in grey weather unfortunatly.
Couple of astro shots with GFX50S + GF 23/4 shot wide-open. Focusing seems quite difficult in pure darkness, as I wish GFX50S had better exposure preview. In other words, I simply can't see the stars, no matter how bright, well enough on the live view/EVF. Maybe it's just me. Nothing wrong with lens and high ISO performance, though
