By now I have a lot of experience on repairs of many early Canon SLRs. They're great to work on, but the one issue I see across them consistently is miscalibration (or previous faulty servicing) of the shutter speeds like 1/8-1/30s. I've seen brief mention that it can be fixed by adjusting the...

It's weird. I've been in both, they seem very different.

Help, I am trying to service broken a canon FT QL mirrorbox (Not FTb) and I cannot find a repair manual or any reference for how the mirrorbox should function. They are different from those in the FTbs which I have worked on before. Does anyone have a reference image or a service manual for...

Thanks for all of the great answers. I guess I just won't worry too much about it then.

Good answer thanks! I don't live in a Radon area, though I still worry about that too.

The day has arrived where I accidentally dropped and broke a thorated lens. I have encountered and repaired a few of them, though I understand it is rarely risky as long as you don't drop or eat them. Well, today I accidentally knocked a box of lens parts off the shelf and SHATTERED the thorated...

I will try this first. The client states the meter worked before, and I have not done any repair related to the meter, or even top access of the camera.

Help!! I have an Olympus OM 2 where the needle doesn't bounce back, despite the speeds auto-firing correctly. Reading other forums, this leads me to believe that the issue is the CDS cells (?) It seems like they are a typical photo resistor, so should I just measure their resistance like I...

The one that feels best in your hand is the one with the best looking photos... Seriously I wish some Leica users would just learn how shooting film works.

Hello all, I have a Canon AE-1 where the curtain is stuck in the cocked position. At first I thought that the mirrorbox needed servicing, but then I notices that it was the curtain that won't release. I have fixed many AE-1s and it is my first time seeing this issue. I've tried to manually...

Yes. I have cleaned TONS of focusing screens with high concentration alcohol and never had an issue with one being ruined. I really thought this one was glass. Though I also cleaned a portion of this one with distilled water and it wore more of it off. I think it just was weak to begin with...

Sounds reasonable... I'd almost rather use a real glass because I don't like how frail that original one was.

That may be the solution to find a generic focusing screen then adjust the prism height, though I don't know how far that travels. I don't like split focus anyways, so it may be worth it to try and make a simple ground glass.

I know that I commented on another reply that the height adjustment is a bad idea, but I'm now realizing that this may be the best camera to try it in since I can adjust that perimeter so easily. What materials would you use to create the ground glass?

That's crazy how the focus screen is tied to a prism height adjustment. Can't even think of where that adjustment would need to be done. Did they design these things with loose tolerances or something?
