Every camera can have focusing problems. Olympus is neither better nor worse in general in this regard.i notice oly camera has poor focusing prob, last time my friend one also like that.
Anyway, what is the point with your comment? Maybe your friend abuses his camera, maybe he doesn't know how to use the camera, for all we know about him from your post. Canon had really had a lot focusing issues a while back and it took them several years to admit there was a problem, maybe you are mistakenly think about that and confuse it with Olympus? :dunno: I hear Sigma lenses has a lot of focus problems, maybe your friend uses those lenses? :dunno:
