Fujifilm XF 56 1.2 (and some other lenses) shutter delay MF

[brixx]

Hi to everyone,

I'm finding this thing very frustrating and don't even understand why it should happen. I'm using two X-T3s and a X-E 3 and it happens on all those cameras (all the firmware are up to date): When in MF I focus with the AF-On (AF-L) button. Then when half pressing the shutter most of the time (but not always!!!) the lens slightly moves the focus motor before being ready to shoot (the focus is always perfect though).

The problem is that if I press the shutter button completely it takes that half a second (doing that little noise) before taking the shot. This is so frustrating when I need to capture the moment. I don't even get why the lens should do it if it's already focused...and on top of that it doesn't happen all of the time. If it does it it's until I focus with the button again, if it doesn't it continues not to do it until I focus again in another spot. It looks like it's random at every new focusing

This never happens with the 18 1.4 or other fast focusing primes, but happens exactly the same with the 27 f2.8 or the 18 f2.0. It looks like it affects standard motor lenses.

Any other experiences on this behaviour?

Thanks!
