But picture quality is the NUMBER ONE reason I want a camera and the number one determining factor of which camera I want.

Then why are you using a Canon 5D? There are cameras with better image quality readily available.

This isn't a troll or a rhetorical question. There's (almost) always a camera that will produce a higher quality image. Better Light makes a scanning back for a 4x5 camera that captures 85 million pixels. Makes a mere 22MP mf back seem chintzy, doesn't it? I can't even begin to imagine the prints that it must make.

There's a reason why neither of us is using it, a point at which picture quality is not the number one determining factor in our camera choices. I've mentioned mine already. What are yours?
