I'm a little concerned, the image preview on my 20D is, quite honestly, pants. utterly hopeless in fact. if I zoom in to check the sharpness of an image it just gets worse and worse... not entirely sure why its so bad but its bugging me, surely the point of having a preview screen is to check focus/sharpness and things like that? cause otherwise using just a 1.8" preview screen is pretty pathetic to check things with...whats it like with you other dSLR owners? is the image you have clean and 'zoom-in-able' whilst retaining quality?
is it just mine or does it happen on yours?
