Olympus OM-30 repair & common faults
Good coverageThe OM-30 (sold as the OM-F in the US) is an early-1980s aperture-priority Olympus SLR, built on the compact OM body but fitted with a viewfinder focus-assist system rather than true autofocus. Its faults mostly trace back to that electronic assist circuit, the aperture-priority metering, and the usual age-related seals and foams common to OM bodies of this period.

Common Olympus OM-30 faults
Olympus OM-30 focus assist not lighting up
The OM-30's party piece was its viewfinder focus indicator, a small electronic aid rather than true autofocus, and on cameras this age the LEDs or the circuit driving them are a common failure point. Worth confirming fresh batteries are fitted first, but if they're still dark it points to the assist electronics themselves, not the lens or the meter.
Olympus OM-30 meter not responding
A dead or frozen meter on an OM-30 is usually down to the battery contacts rather than the meter cell itself, corrosion and dirt build up here over decades and break the circuit. Try fresh cells seated firmly first. If the needle or readout still won't move, the fault sits deeper in the metering circuit and is worth having looked at.
Olympus OM-30 shutter speeds inconsistent
This is an electronically timed shutter, so speed accuracy depends on ageing capacitors and contacts rather than any mechanical governor. Inconsistent or drifting exposures, especially at slower speeds, point to that timing circuit rather than anything the owner can adjust. It's a genuine electronic fault and generally not something battery freshness will fix.
Olympus OM-30 viewfinder dark or dim
A dim or patchy viewfinder on a camera this age is most often the mirror bumper foam breaking down, which lets the mirror sit or bounce slightly out of position, or in some cases haze building up on the internal optics. Neither is something to check without opening the body, but it's a well known ageing fault on OM bodies of this generation.
Olympus OM-30 light leaks on film
Unexplained fogging or bands of light on developed film almost always trace back to the foam door seals, which perish and compress with age on every OM body of this period. Worth checking the seals aren't visibly crumbling or gummy around the door edge, though by this age most haven't been replaced and are due for it.
