Hello,
I just finished my film simulation LUT pack for the X-H2s. It includes all the film simulations you can find in the X-H2s (except for Acros, Monochrome, Sepia) which you can apply to your F-Log or F-Log2 clips.
You can find all the details here: https://colorizer.net/index.php?op=xh2s
Demo video: https://youtu.be/zjOBKMpR0ag
The implementation of F-Log in the X-H2s is slightly different from that of the X-H2/X-T5/X100VI, but the difference is minimal, you might be able to use this LUT pack on those cameras as well. I'll gladly apply all the LUTs to your test clips before purchase.
