To my knowledge, on the X-T2 aperture control with the front dial only works with lenses that do not have a dedicated aperture ring.

I was referring to the current 3rd generation of Fujifilm bodies, where this is different. And yes, they are highly customizable. For example, up to 3 functions can be assigned to the front dial (including aperture control), one can quickly cycle through them by just pressing the front dial (long press it to quickly access the setup menu for the dial).

And yes, I find the AUTO-ISO on the X-T30 far superior over the implementation in the Z50 (not Nikon in general). There are three profiles available, so you can create one for wide, normal and tele. Yes, it's 'deep in the menus'... as it is on the Nikon, too (even though to me it's just a different menu structure compared to Nikon, not necessarily a worse one).

The Z50 has only one Auto-ISO profile, it's not focal length dependent. Also, unlike on the X-T30, you can not set a default ISO, just maximum ISO and minimum shutter speed, that's it. I'm sorry I seem to be too blind to see the superiority of this approach
