Help! XH1 ISO defaults to 800 in F-Log

[trampenau]

I've been using my XH1 for a couple of weeks and have been shooting video. Recently when I shoot in F-Log I cant get the ISO below 800, it will let me choose a higher ISO but when I drop to 800 the ISO turns yellow and wont let me choose a lower setting. Am I being daft or have I clicked an auto setting by mistake I don't know about ? Any help or advise would be great.

Looks like the camera has DR 400% setting selected

I have the same problem, but DR 100% is selected

I suppose some video setting has influenced photo setting. Do a control of video setting

It is normal, 800 iso is minimum for log. unfortunately this setting shows a lot of hot pixels in my camera, so much I will ask for return

ISO 800 is expected for F-Log, same on the X-T3.

It's a reason why F-Log is not so great if you don't need the extra Dynamic Range. You get more noise, but also you can lose some midrange information.

Use F-log only if you won't be using the Eterna LUT and will do your own grade + You really need the maximum dynamic range because you can't control your lighting + You don't mind being at ISO 800 as you would need it anyway (semi-dark environment)

If you use Eterna in the end there is little point to using F-log, you're just adding an extra step to the process and shooting at ISO800 when you could be shooting at ISO200.

Yep, that's normal base ISO for F-Log recording. Manual, page 141.
