M.Zuiko 45mm/f1.8 acting strangely?
I recently purchased this lens for my fantastic OM-D EM-5. So far it's proven to be a great lens with nice OOF when shooting wide open, but I think mine is behaving strangely. When powering up the camera I can see (and hear) the lens iris varying continuously, adapting to the changing light hitting the camera sensor according to where I point the lens at. It does this without depressing the shutter button halfway or pushing any other buttons. Sometimes the lens stops acting like that after taking it off the body and remounting it.
I can also hear a very faint continuous 'fan noise' in the camera body - not the well known fan noise of the ISIS, which is louder anyway (and now occurs only when depressing the shutter button halway bcs the camera has been updated to firmware 1.5) With the 12-50mm kit zoom lens the iris does not move at all when powering up the camera.
Any ideas please? Thanks in advance for your help. Ben
