Sounds like your friend has 1 of the medical versions of the Pen F (to be used w/microscopes, etc.).

I took the 40mm F1.4 lens off and the the area where the mirror reflects into is round. I can't help but believe there is a piece missing that covers that area. Is my guess correct or is there someway to change the viewfinder?
Thanks for any help.
