[OM] Zuiko 90/2.0 - sticky diaphragm

Hello!

I have a kind of a problem with my zuiko 90/2.0 macro. If the aperture is set 
to 8-22 and when I push the stop-down button and then release it THE DIAPHGRAM 
DOES NOT FREELY OPEN. I meant that the diaphgram stays stopped down. I have to 
shake the camera or touch slightly the aperture ring to release the diaphgram 
again.


Now I would like to ask: 
Is this a common problem (especially with 90/2.0)? Is it likely an expensive or 
a cheap repair to fix this problem? And btw, what could cause this stickiness? 
Is it a mechanical problem, or just dirt or have the lubricants wandered to a 
wrong place?

Thanks!!

Olli
