The L35AF (and cousins) fail from dead light seals, sticky lenses, and tired capacitors more than from “mystery electronics.” Start with seals and a CLA mindset.
Practical tips
- Replace degraded light seal foam to stop foggy frames.
- Exercise the lens carefully—do not force a stuck helicoid dry.
- Battery contacts corrode; clean with proper contact cleaner.
- Test with cheap film before important shoots.
Safety notes
Ultrasonic cleaning of lens groups is specialist work—separating cemented elements ruins coatings.
