[QUOTE="wornish, post: 424744, member: 15434"] One way to check if its light leaking through the viewfinder is to take shots with the lens cap on at say two different iso settings, 640 and 6400 all with camera set in manual at the same shutter speed and f/3.5 aperture and the viewfinder cover open , then repeat with viewfinder cover closed. Heres some I just tried. I purposely held the camera with the back towards the window. The only one I got any noise on was iso6400, 10 secs with the viewfinder cover open. With it closed it was completely black. all the others were black. iso6400 10 sec cover open, some noise as expected.
