Hi Folks,

I want to swap out the glass in a f100's viewfinder. Anyone know how to get it out?

When you say 'the glass in a f100's viewfinder', do you mean the focus screen, or the window you put your eye up to? To change the focus screen, it's on pg 65 of the manual. For the other, my guess would be disassembly of the top would be needed.

The window. Not the piece you unscrew. The glass behind that. It's in the body. My working f100 has a cracked one. My "for parts" f100 has a good one. But I have no clue how to swap them.

That's the way alright. The lens frame is likely held in by two screws, it's getting in there
that's the kicker.

Can't you just swap the tops? I'm not familiar with the F100, but looking at the parts list diagrams, looks like it can be done with some patience. I'd use the 'for parts' body to practice on. :smile:

Hmm, maybe I should just be asking how to get the top off of an f100. I got through the area around the window by tearing off the plastic. The glass under that is the adjustable diopter. It's about the size of a thumbnail and it's convex. Under that is another piece of glass...

*Well I go the top off. There are a lot of screws under the rubber, about 5. It's not worth it because you must pull the rubber off. I don't know how to put it back.

Clean the surfaces with q-tip and adhesive remover. Then you can use thin double-sided adhesive tape to put the rubber back on. If this is not available, contact cement can also be used. When putting the rubber back on, be very careful about right position. I usually choose a certain border to line up and put that on as accurately as possible. After that, the rest of the rubber will just fit into place without any effort.
