Hey guys,

Just picked up a used K-5 for a friend of mine (one Pentaxian more!

).
Tried the camera out and it seems well looked after but used (shutter count ~17k) and functions well, however what I thought was the screw drive doing something when turning the camera on turns out to be the aperture lever.
It vibrates up and down ever so slightly. It's barely visible when looking at it when turning it on but you can clearly feel it if you place your finger on it lightly.
Is this a common issue? Is there a fix? Does it matter? It simply doesn't sound great with a lens attached as it rattles the aperture around a little, but it did strike me as a little odd!

Cheers

Are you sure it is not automatic sensor cleaning in operation ?

Yes, I was thinking/hoping it'd be that at first but it's definitely not that.
Can post a video tomorrow in daylight.

Missed daylight by a mile, but here's a video.
Movement happens when turning the camera on.

Just checked my K-5. Does the exact same thing. Probably a "zeroing" of the position routine. Looks normal to me.

Thanks! Glad to hear that

Just wanted to make sure before I drop the camera off by my friend. Was a bit uncertain since my K-50 and K-1 don't do anything like it.
