Originally posted by gavinhw I just got one. It’ll be my Birds In Flight camera. I’ll leave the macro and landscape stuff for my K-1. I wanted to use the X-T3’s front and rear dials to control the aperture and shutter respectively, à la K-1, but alas, that is simply not possible, so my muscle memory has to consider another workflow. BTW, I shot with Pentax SLRs back in the 80s, so using the aperture ring on my new Fujinon lens and the top-mounted shutter speed control on the X-T3 is not a big issue. But still.
Update.
If one sets the top-plate shutter dial to "T", then the shutter speed e-dial, which I believe is by default the rear e-dial, has access to the full range of speeds, not just the +/- 2/3 stop range centered around the top-plate shutter dial value.
I also put all my XF lenses in "A" mode, and through some other setting (I forget which), I am able to use the front e-dial to set the aperture.
In effect, you bypass the mechanical aperture ring and shutter dial.
Lastly, I set the ISO dial to "A", and configure my camera's AUTO ISO with a minimum shutter speed value. The camera will automatically adjust the ISO whenever that minimum shutter speed cannot be satisfied. This means T and Av will be honoured, and ISO is dependent on those two settings. Exposure compensation is at the expense of shutter speed whenever the minimum shutter speed can still be maintained; otherwise, it is at the expense of ISO.
The net is you are in manual mode with Auto ISO.

Another Update.
Currently, I am experimenting (with above customized settings) with having the mechanical shutter dial, my lenses, and the ISO dial all set to “A”. You are in aperture priority mode with auto ISO, and using the front e-dial. No need to futz with the aperture ring or dedicated mechanical dials.
