need help with 580EX ii on my 70D
4 months ago

I only need a speedlight a few times a year, and just received a 580EX ii. In testing it last night in a moderately lighted room, set to ETTL, I could only get dark, muddy results.

ISO seems to be stuck on 400, aperture on f4 and shutter on 1/60 in TV, AV, and P modes. In full auto mode it ramps up to ISO 1600 with lousy, dark results. I set upper limits on ISO to 12000.

This was with ISO set to Auto. I'm reading but not finding my problem. Help please!
