I apologize for the thread resurrection here, but it would be nice if the camera would at least remember where you had manually focused it to. (If there's a setting for that somewhere that I missed please point it out!) I often zone focus and as soon as the camera sleeps or I shut it off, the focus point resets to about the two meter mark. I assume it's the same on the X-Pro2. A great firmware update would be to enable the camera to remember it's position, and/or to at least reset to hyperfocal distance (as they calculate it) for the given aperture.

I have to admit that I haven't seen this issue as I never zone focus anymore. I find with the X-Trans III cameras, the AF works well enough for me.

How would/could firmware remember a manual position? Just reset the lens.

I have the 14mm f2.8 and 23mm f1.4. Both have the AF/MF clutch and when the clutch is pulled back to MF mode, my X-E2 will be at the same focus point when I turn it off and then turn it on as long as I don't move the focus ring. These lenses are still operating on the same focus by wire that the AF system uses, but now, they have hard stops at minimum focus and infinity just like fully manual lenses do. This provides the firmware with two calibrated end points and a known focus point in between to tell the motors where to keep the lens focused. I had the same system with three of my Olympus lenses and it operated the same way. However, for whatever reason, the lens designers decided to remove the hard stops on AF lens focus rings so you can just spin them forever and there is no accurate way to measure and record the focus point.
