Ricky_the_Joker Posted June 6 Share #1 Posted June 6 Advertisement (gone after registration) Hi, I have a quiet new experience for me. I bought a second hand R3 in quite good condition. I cleaned it up a bit and shot a role of film to test it. Yesterday I developed the film and it seems like only some parts of the film were exposed. I have like 9 exposed images the rest of the film is „empty“. The unexposed parts are clear and numbers are available so for me it seems to be a problem with the camera, which I narrowed down to three possible issues: - shutter sticks sometimes - mirror sticks sometimes - lenses I used two different lenses and on both it happens, also they look super clean and work well when I tried them manually, so I tend to seek it more in the body. But also the shutter and mirror seem to work correctly. I tried different speeds and multiple combinations, open and closed and so on. The only thing is that on the day I shot the film it was very hot and today it’s colder, so maybe the mirror damper is stickier if it’s hot? Does anyone has an idea what else it could be or how I can test and narrow it down to find the problem? I added two images of the developed film. Welcome, dear visitor!

Carlos cruz Posted June 6 Share #2 Posted June 6 Judging from sprocket hole shadows something went south either in developing tank or before winding film back to canister. Link to post Share on other sites More sharing options...

Sorry that just a bad image, the film is completely clear: Welcome, dear visitor!

My bad, I’d dry run a camera through all shutter speeds with both lenses and without lens attached with back open against bright light and observe shutter behaviour. You should be seeing at least blick of light on high speeds and full shutter cycle in slow speeds. You could use high speed video on your phone to diagnose better. But looks like CLA at the very least is a must. If the shutter was only sticking there still would be image in the frame, usually over exposed. It rather looks like it didn’t open at all. I don’t suppose it’s a cap on lens situation. Edited June 6 by Carlos cruz Link to post Share on other sites More sharing options...
Ricky_the_Joker Posted June 6 Author Share #5 Posted June 6 Thanks! I tried it out and it works on all speeds except 1000, here I can’t even see through with filmed slow motion…but why? I mean the shutter moves… even if the timing is a bit wrong, there are way faster shutter speeds on modern cameras, so I don’t get it that it’s completely closed but moving 🤔 At least that probably explains the result. what’s CLA btw? And I don’t even have a lens cap for this lens 😅🙈 Link to post Share on other sites More sharing options...

Ricky_the_Joker Posted June 6 Author Share #7 Posted June 6 Advertisement (gone after registration) The R3, at least the electronic, has a metal shutter. Ok thanks! I‘ll see what I can maybe do by myself and/or if repair makes sense. thanks for locating the problem! Link to post Share on other sites More sharing options...
Carlos cruz Posted June 6 Share #8 Posted June 6 (edited) If cleaning doesn’t help I guess you can find minolta parts donor with matching blood type. Edit: Apparently the problem runs in the family, so financially repair/transplantation might not make much sense. If I was to buy a camera from 70’s I’d rather invest in 100% mechanical one, shutter on r3 is electronically governed and probably electronics are the source of your problem. Good luck Edited June 6 by Carlos cruz 1 Link to post Share on other sites More sharing options...
earleygallery Posted June 6 Share #9 Posted June 6 The R3 can fail for a few reasons, usually the auto exposure metering fails or the shutter fails, I think your shutter is failing. I had one from new and one day some photos didn't come out (like yours). The shutter fires but at 1/1000 (and sometimes on 1/500) it fails to open. I took mine to a Leica repair specialist but was told it couldn't be repaired. If you remove the lens, open the back and point the camera at strong light and fire the shutter at those higher speeds you will see if the shutter is actutally opening or not. 1 Link to post Share on other sites More sharing options...
Ricky_the_Joker Posted June 6 Author Share #10 Posted June 6 Funnily it seems to work on auto mode. Just tested it and there it always opens. Problem is that my summicron 50 is the old one step version from the SL, so I could only use it on aperture 2 or I use the zoom (that’s a three step version). I think I try it with another film on auto mode, because I wanted to take it to sardegna next week. but probably on long view it will be another body. Maybe SL again. 1 Link to post Share on other sites More sharing options...

I'm guessing but probably on auto the shutter speed is stepless, so it's only failing when it's at 1/1000th. Just stick to 1/500 max (assuming it's opening reliably at that speed).
