Yes, Focus shift has a work around. I need to check on your 2nd point, as I am not sure.
Fuji, with their Focus by wire, design has plus and minus problems. The issue I have with the FBW for the GFX is:
When you turn off the camera, your focus point is lost
When you move from capture to playback, your focus point is lost
When you move from S mode after obtaining a good focus, to M mode, your focus point is lost
In the past on primes, Fuji allowed for a Manual focus clutch, so you can focus, then clutch down to MF, then go back and forth between capture and playback without the loss of your focus point. So far none of the GFX lenses have a clutch, which I feel is a huge oversight by Fuji, at least for my work.
