Hi everyone! I have a question about GFX RF. As I am new with Fuji I can't find a way to set the EVF and OVF not to show the real effect of exposure compensation while I am working in A. I only see the possibility to set on and off the OVF/EVF preview exposure in M. I am asking because I got the speed light EF 60 and I want to use it in daylight in TTL while keeping the Ambient light between -2 and in some cases also at -5 but when I do so I can't see properly the image. I always do this on my Sony's and I wonder if I can do so with a fuji. Thank you in advance Lorenzo
