Yes, if you see out of focus floating dots in the finder, they are probably
defects in the prism coating.

Subject: [OM] OM 2 SP / Viewfinder
| 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
|
