Originally posted by robroy Can someone verify how the manual focusing should work with K-r? In my camera there seems to be something wierd in it. It's very inconsistent. I haven't had a Pentax camera before.
When I press the shutter release button halfway down and rotate the focusing ring (slowly) in the manual focusing mode, often the focusing indicator (that green diamond) doesn't light up at all. When it does light up, it immediately goes off.
you need to turn the focusing collar slowly, if you go too fast, you can move through focus before the indication comes on, or move through it and get a transient indication. Note that you need a sharp contrast point usually to get focus, either a line or something, but not a plain zero contrast surface

yes
Quote: When I release the button, camera sometimes beeps later on as it would have focused. I feel that strange. Is it normal behaviour?
yes, to an extent. when you press the shutter release half way this activates the metering and in focus indication, they stay on for a pre-defined time after letting go of the button
