These cameras did NOT age well. I purchased my 1st AX-3 when they were first released. It was in for repair within a year (don't remember why, but I would bet it was the shutter). After about 10 years of casual use (think less than 200 rolls of film) the film advance jammed and I never got it fixed. When my kids got old enough to learn 35mm photography, I purchased a few used bodies on Ebay because I already had glass for AX cameras. After purchasing 4 bodies, including one that was "new old stock" I gave up. The "new old stock" camera was just that, pristine condition, original manufacurer's packing, unused. I popped a battery in her and it NEVER got the chance to shoot film. It took about 5 "exposures" while checking the shutter speeds for the shutter to stop working :-( . The other bodies had a wide assortment of problems including light leaks, shutters that only worked on one speed, meters that wouldn't work. I was hoping to find a body that only needed new light seals, but give up before ever finding one.
I've since moved on and have acquired a Nikon system based on 3 FM3-A bodies and couldn't be happier. As much as I was disappointed in the AX-3s, there is (or at least was) LOTS of cheap Nikon 35mm glass on the market.
