Cleaning Olympus OM-2n focusing screen

[p.giannakis]

Hi guys,

I recently bought an Olympus OM-2n and it seems that the deteriorating mirror buffer has spread to a place on the focusing screen.
I removed the focusing screen and seems to be made out of plastic. I cleaned it a bit with a damp cloth but not much came out.
How should i attempt to clean it? I am a bit hesitant to use lighter fluid as i am afraid this will damage the plastic screen.
What would you recommend?

Hi,

In your shoes I'd look on ebay and buy another screen as they are cheap enough: well, mine was.

Better still get the thing looked at and sorted out by someone like Micheal Spencer or Luton Camera Repairs, I can recommend both for Olympus cameras. You've a good chance at present, I hope, to get the prism sorted out but may not in a few years time.

Regards, David

I don't THINK that either lighter fluid or isopropyl alcohol will damage the screen; however, getting the black goop out of the grooves of the Fresnel lens pattern on the screen may be very difficult without some rubbing, and the rubbing WILL leave visible scratches on the screen. An ultrasonic cleaner is probably the best approach here.

I use isopropyl alcohol w no issues

Remove the screen soak it in lukewarm water with dish-washing detergent and rinse thoroughly. Do not rub it or you will mar its mate surface.
