Originally posted by TER-OR Yeah, that's an annoying beep because it's not focus confirmation, just telling you a focus point is active.
I agree that the beep can be annoying, but on my cameras (K-3 and recently departed K10D), it happens at the same time as the green hexagon as an indication of focus acquisition. This is explicitly stated on page 32 of the K-3 manual. It is sort of nice in a way if you are tracking a subject and want to keep your eye on the viewfinder frame. Perhaps it would be good to point out that the volume is adjustable as well.
