Hi everybody,

When i put my K01 in Av mode, with AF/s, and i move the cam i hear, at about every move, a klicking-like sound. In finding out how come i looked into the lens and think i saw the diaphragma opening and closing every time i point and something else. This is done automatically by the cam: i'm leaving all buttons free.

Is this a standard 'thing' or else ?

Hope somebody here knows the answer and thanks in advance. :-)

It is normal. I think the camera is keeping a certain aperture to maintain the brightness of the display and as you point it at different scene brightness, it changes the aperture accordingly.

Thank u all... i'm very happy, don't have to be worried, my k-01 =ok :-).

Nice!
 
Btw, this is only in Av mode. Using e.g. the Tamron17-50F2.8 ... :-)...
 
Why is it happening only in Av mode ? I am guessing that it has something to do with the fact that in Av Mode You are the one who sets the aperture, while in other modes, it's the camera.
