I was out shooting my Olympus ECR and have somehow picked up a light colored fleck in between the lens and shutter (old adhesive?)... well, it is ruining photos. If I tap the camera it will fall to the edge of the inner barrel, but obviously, not ideal and I want to fix it. On a worthless camera I got for free I'm not considering paying for service. Just looking for a advice on cleaning the lens (I think it's the same as all the others in the Oly series of RF's). Specifically, if I remove the front retaining ring, will the lens elements drop out so I can blow out shutter area and get that fleck out? If not, should I try removing the rear elements and blowing out from the rear? Thanks for all help and advice! I really want to get this camera back in reliable service.
