Help Please: AF box jumps erratically with new X-T5

[S. Miller]

Hi,

I'm 99.9% this is user error but can't figure out what I'm doing wrong. I have a new X-T5 and can't figure out why when I set the single point focus box on a given area, as soon as I half press the shutter, the AF box moves (up, down, left, right, whichever way it wants to go). It's so bad that when I half press the shutter, and see the box move, even when I manually try to keep the box in place by moving the AF joystick, the box still moves.

I'll list what I think are the relative settings I'm shooting with but please ask for any other settings I may be leaving out.

• Happens with AF-S or AF-C
• Single Point AF Mode and have varied the size of the AF box but the problem still occurs regardless of the box size
• Store AF Mode by Orientation: ON
• AF Point Display: Off
• 425 focus points
• Pre-AF: Off
• Face/eye Detection: Off
• Subject Detection: Off
• AF+MF: On
• MF Assist: Peak
• Interlock Spot AE & Focus Area: On (no clue what this is)
• AF Range Limiter: Off
• Touch Screen Mode: Area (I'm not accidentally touching the screen and causing this issue)

It happened frequently when I went out for a walk. It's very sunny but I don't see why that would be an issue. That said, now when I test it indoors, I don't have the issue. Very strange!

Any thoughts? I have to have some setting off or am doing something wrong.

Thanks in advance!

Steve

P.S. I'm using the XF 16-50 f/2.8-4.8 with firmware 1.00. I see conflicting info on the web about whether there's a more recent firmware. When I checked Fuji's site, I didn't see any firmware update listed for this lens.

I had the same problem with my X-T5. The reason was a manual setting in the "AF-C custom settings -> set 6 custom" menu. After switching to set1, set2, etc., the problem disappeared. Firmware ver 4.31
