Hi. I just but fuji xs10 with 23mm f1.4 lm wr. When input the lens. And set the auto iso. Base iso is 160 and maximum is 12800. Minimum shutter speed is auto

now. The minimum shutter speed is always 1/100

according what i read on manual. If min shutter speed set to auto, camera will set min shutter speed 1/… according to the lens attached. So it must be 1/20 if i put a 23mm lens

has anybody ever experienced this

I rarely shoot below 1/125" at 23mm if anything is moving in the frame (people). The Auto minimum SS mode actually tends to choose too low a SS in many situations. I recommend three presets, all at base ISO to 12800, each with a different minimum SS setting - typically 1/80", 1/160", 1/320" for my X100V (23mm). IBIS is swell, but it won't help with subject motion. If you're shooting static subjects in low light then, sure, set lower SS presets, but I would avoid very low shutter speeds for general purpose shooting.

The Auto min. SS feature is too unreliable in its current implementation, IMO.
