FM2 viewfinder eyepiece

Hello. I have just bought a FM2 with the DK3 eyecup. However, when I tried to screw it in the rubber that surrounds the viewfinder peeled off. When I searched on the web I have found out that I needed a replacement eyepiece finder. Now that the eyepiece rubber fell off, and there are no threads anymore, do I need to get it fixed, or will the eyepiece finder fit without the threads? Thanks. Edited December 18, 2017 by craxionne

B & H has them and I think they are in stock. have bought several in the last 2 years.

The FE/FM series typically have a chrome ring surrounding the eyepiece. I forget exactly how this is attached, but it would be exceptionally uncommon for it to be missing. The chrome ring has threads on the inside to accept the screw-in eyepiece.

is the plain "rubber bumper" ring that surrounds the eyepiece. As an eyeglass wearer, I prefer this to a larger cup as the eye relief is fairly low on FM and FE series cameras(plus the Nikkormats, F, F2, and non-HP F3) and the bumper protects my glasses while still allowing me to get close enough to see MOST of the viewfinder.

 

If you want a full eyecup, you need a DK-3. NikonDK-3 Rubber Eyecup for FM3a, FM2, FE2 & FA Cameras

Years ago (1980's) I had a non-Nikon eyecup that was held on by the eyepiece.

 

The result was that the eyepiece wasn't held on as well as otherwise, and at some point got loose and fell off.

 

After buying a replacement, I decided not to risk it again.

 

I don't remember if I had the eye relief problem mentioned, though I do wear glasses.
