Originally posted by Wingincamera My Pentax cameras didn't give a focus beep either but I still had the green hexagon illumination, Then I happened to mention it to my wife and she assured me that the camera beeps every time. I couldn't hear it. So I turned it off in the menu, no since bothering other people. Some day I will have to get hearing aids.
We had a question about this some years back and for that person, it turned out just as you said. Someone suggested he go get his wife and have her listen. Yep...it was beeping. For me, it was one of my flashes. It was showing that it was powered up, but it wasn't giving me a confirmation beep. Or so I thought. I eventually changed the hand I was holding it in and suddenly I could hear it. This may not be what the OP's problem is, but it's sure the first thing I would check.
