Well i was thinking it'll make things easier and when i get pw's prvided i get a compatable one they will link together so as to always get the right flash exposure etc.
I know a few people who use them with dslr's, and you can't always tell if the exposure is correct on the backscreen i don't think.
True about the screen on the back, I've never really had a problem with mine but some other cameras may be harder to see.
