If I could sidetrack on this thread: I have trouble losing the Rubber Eyecup on the 645D. They simply pop off very easily when wearing a coat, and arm rubs against it. I have replaced several times, and even Superglue the last one on. Lost it too. Adorama and BH both out of stock, i assume due to everyone else losing theirs too. Any tips on how to lock them down permanently?

As for topic, I have 75 and 45 in both MF and AF, and the 35MF and 55MF -- all of them are stellar, to me. And most of them averaged around $200 for great condition, at KEH, for the MF models. Amazingly affordable. I love the camera, except for the vastly underpowered writing engine. I hit the buffer very often.

If you wear glasses, you could always superglue one of the eyecups to your right eyeglass lens. 

P.S.  If you don't wear glasses I would disregard this suggestion.

For the eye cup you need to make a little rigid collar to go over the camera side of the eye cup.

The problem is that the eye cup is made of nice comfy soft rubber.

This soft rubber is not tight enough where it fits over the camera.

I found a nylon casket ring that fitted over it nice and snug. Tricky to get on, but once there it did not move.

It was my friends camera and it's still on a year later.

Nylon o ring/gasket thingy like this, but bigger and slimmer.
