Hey everyone, father's birthday is approaching, and he enjoys photography but hasn't done much of it in a while as he doesn't have an appropriate camera. Used to use an old Minolta all the time, but since the days of digital he's just had a point and shoot. Long story short, I'll be getting him a camera as a gift, and was looking at the G3 deal as it's on for $300 right now. Coming from a film camera, however, I know he will want to use the viewfinder over the screen. I've heard the quality is good, but is it good as in a substitute for an optical viewfinder? Would it be doable to use manual focus with it? Thanks!
