Both cameras need a CLA/Overhaul to be in tip-top condition. I think they are worth repairing, but because they are so rare (and old) it has been difficult to find a shop willing to work on them. After a lot of searching, I found a place down in Portland, OR that will look at them and give me an estimate. I have written up descriptions of all the various issues with each camera body. I am not sure I want to trust the USPS with these rare bodies (the f 2.0 model is the only one I've seen😱) Here's the write-up:
Mamiya Camera #782605
Model: Magazine 35
Lens: 4.8cm f2.0
Problems/Condition:
• Advance Lever is “gritty”- not smooth
• 1/500 second speed does not work
• Slow Speeds are inconsistent- usually fires at a higher speeds
• Shutter release button is TOO Firm- you have to press hard to activate
• Removable magazine/back has a tight winding spool (right side- the silver one with gears)
Other functions- Rangefinder, Viewfinder, Rewind, Aperture, Speed selector, Focus, etc. all seem OK. I have shot film with the camera and had good results- The main issue is the shutter release button
Mamiya Camera #782070
Model: Magazine 35
Lens: 5cm f2.8
Problems/Condition:
• Advance Lever is smooth BUT does not return quickly
• 1/500 second speed does not work
• Shutter is inconsistent- sometimes fires fine- other times with a delay
• Shutter release button is inconsistent- sometime only a light touch activates, other time a firm press is needed
• Removable magazine/back has a tight tensioning spool (left side- the thin silver one)- doesn’t spin freely
• Rangefinder Window is loose/crooked- MOVES when the shutter is fired!
Other functions- Rangefinder, Viewfinder, Rewind, Aperture, Speed selector, Focus, etc. all seem OK. I have shot film with the camera and had good results- The main issue is the erratic shutter.
