Why does my XT-4 still attempt to focus despite being in manual mode?

[SHUTTER AF]

Choose whether the camera focuses when the shutter button is pressed halfway.

[AF-S]OptionDescription

[ON]Focus locks when the shutter button is pressed halfway.

[OFF]No focus operation is performed when the shutter button is pressed halfway.

This, combined with what Erik is stating about stop-down depth of field, is most of the answer to the question.

Many of us who rely mostly on the MF setting will opt for Shutter AF [OFF] setting, and then assign one of the back buttons (or rear command wheel) to AF ON: called back button focus - or BBF. This is especially helpful with Fuji bodies because, frankly, the squishy and imprecise feel of the shutter release button (slightly improved on the X-T5 but still not very good) tend to cause a lot of misfocusing problems.

Shutter AF is disabled automatically in MF mode, so no reason to disable it if you prefer it for other modes (which I very much do). I do have my rear command dial set up for AF On for instant BBF in M mode to quickly get focus in the ballpark.

Way back when I switched to BBF I found that it was quite an adjustment for a few days, and then it became natural to me. For me, muscle memory is a challenge if I'm shooting in multiple ways, so I try to keep everything set up mostly the same way for all situations. So, I'm shooting BBF in all situations.

i use BBF in Manual focusing mode all the time, but never with AF-S and AF-C. Despite much experimentation, I have never been able to get BBC results with anywhere near the consistent accuracy that I get using the shutter button for AF with Fuji cameras, especially with moving subjects. If full-time BBF works for you, great, but it doesn't work well for me at all. Just flipping the front MCS button and I'm instantly from BBF with manual fine-tuning, to fast/accurate AF with the shutter button, the best of both worlds, IMO.

I should experiment with that. I'm not entirely happy with how the X-T5 is responding on AF with moving objects (AF-c). I don't do a lot of action - so had chalked it up to that, but the XF 70-300 has been more frustrating than expected in testing. Still winter here, so very limited real action shooting.
