Dear List,

I have succumbed to the purchase of a very beautiful mint OM-2 SP camera body today. I checked it out as best as I could in the shop but I didn't have tweezers to have a look at the focusing screen although all indications with the camera were that it had seen a few rolls of film followed by extended storage. It has the Green LED for the flash indicator so it is the battery hungry version. It has no brassing at all and all the covers are present.

Problem (maybe): I got it home and started checking it out thoroughly. The functions all seem to work correctly. I removed the focussing screen and installed my 2-4 screen. Looked through the viewfinder.... FUNGUS!! a spot of it at the edges of the viewfinder. I took out the screen and looked inside. The pentaprism lower surface had two spots of fungus that came off easily with a cotton tip. Reinstalled the screen and the fungus was gone.

Now, I removed the screen again and looked through the viewfinder. I saw some blurred images of fungal spots that it was impossible to focus on clearly with my eye. There were several of them all out of focus. I checked the mirror and there was no marks or fungus. So I re-installed the screen and tried looking for the fungus and couldn't see any.

My guess is that they are on the surfaces of the pentaprism not available to routine cleaning by the user. It doesn't interfere with viewing the image at all with the focus screen installed. The viewfinder is otherwise ok and I can't see any desilvering although I don't really know what to look for with this.

My question: What should I do? The camera is otherwise absolutely perfect. Should I have the camera cleaned for this alone. How difficult is the cleaning? I got it for a reasonable price. I have never seen this problem before and would appreciate any advice on what I should do.

Thanks
