D800 setup issues???
So I shot my first wedding with the D800 and ran in to a few things I would consider issues. My camera was in Aperture priority mode with Auto ISO with a max ISO of 3200 as the venue was very dark. When I would focus/expose on the bride then recompose the image, my ISO would change. I thought holding the shutter half way down would lock in the settings until I either took the image or let up on the shutter release. The same thing happened with my shutter speed. Is there a setting within my camera that will ensure holding the shutter halfway down keeps the settings until I take the shot?
