Ricoh 500 G repair & common faults
Fair coverageThe Ricoh 500 G is a compact manual rangefinder from Ricoh's 500 series, built with no light meter and no battery dependence, so every setting is judged and set by hand. The leaf shutter lives inside the lens barrel rather than the body, and the viewfinder and rangefinder are a separate optical assembly behind the top plate, which is where most of this camera's known problems actually sit.

Common Ricoh 500 G faults
Ricoh 500 G light leaks on developed film
Fogged edges, streaks or patchy exposure on the negatives rather than the viewfinder points to the foam light seals around the back door and door rollers, which perish with age and are a well-known weak spot on this model. Open the back in good light and check whether the black foam at the door edges looks crumbly, sticky or missing, that alone usually confirms it.
Ricoh 500 G hazy or dim viewfinder
A dim, hazy or spotted view through the eyepiece is almost always fungus or old haze on the viewfinder or rangefinder optics rather than the taking lens, since the two are separate assemblies on this body. It won't touch the negatives, but it makes framing and focusing harder, and fungus left alone will etch the glass permanently over time.
Ricoh 500 G rangefinder double image won't align
If the two halves of the rangefinder patch won't merge at true focus, the mirror or arm behind the viewfinder has drifted out of adjustment, which is common on a camera this age rather than a sign of anything else failing. Focus simply can't be trusted until it's reset. Check against a distant object at infinity first, before assuming the lens itself is the problem.
Ricoh 500 G shutter sticking or slow speeds sound the same
The Seikosha-MXL leaf shutter sits inside the lens rather than the body, so hesitation, a shutter that won't release cleanly, or slow speeds all sounding alike usually means old lubricant has gummed the blades rather than anything electrical, since this camera has no shutter electronics to fail. Fire it empty across a few speeds and listen for one that clearly drags.
Ricoh 500 G shutter release button loose or wobbly
A shutter release that feels loose, sits crooked or doesn't return cleanly is usually the button having worked free of its seat under the top plate rather than a shutter fault, and it's a common complaint on well-used examples of this camera. It looks worse than it is. Check that it still depresses squarely and fires before assuming the shutter mechanism itself is at fault.
