I wear the X-E2 on a neck strap, cross body, under the left arm ~ so, for me, the 27mm makes that camera almost unnoticeable...but, with the Fujicron 35mm f/2, I'm much more aware of the camera. And...I'm discovering that my dominant (right) eyes tends to "see" in 40-43mm, rather than in 52-53mm.
I have not found a way to access the extended ISO range on my X-T200, whether I am in normal or fine image mode and there is nothing anywhere else on the web that addresses this. Perhaps you got this confused with a different model of Fujifilm camera and this is not actually a feature available on the X-T200?
Interesting. I'm on firmware 1.01 for X-S10.
X Webcam 2 doesn't detect the camera. But X Acquire does and I can save camera settings to a file.
I also have an X-T200 and a6400. With X-T200 the :regular webcam works and but definitely not compatible with X Webcam 2.
Even on a newer, clean-install computer, no luck with X-S10 and X Webcam 2.
