I went to shoot this week with my Z8 and a flash on a bracket with ttl cord. It was indoor in a dark room at f8 at 1/250th of a second at iso 3200 or 6400 and when I looked through the electronic viewfinder. the image was very dark - it was although I had pressed a depth of field preview button and the aperture stopped down to f8. I didn't intentionally change any of the "normal" settings that I shoot with. I'm new to the Z8 and haven't shot many indoor scenes, but I have never had the viewfinder darken so much. Any idea what I actually set to get this stopped down view?
