Probably not often enough. I have to stick my reading glasses on now if I have to look at camera setting etc. ( ageing eyes ). Mainly to check when I am exposure compensating or if I think the subject moved whilst the mirror was blocking my view ( flowers in the wind ). I find the screen too dim in bright outdoor light anyway to see anything of much use. Like other birders too busy keeping an eye on the subject. ( It's the little one that never sit still for 2 seconds )
