The Olympus OM-2 takes everything people love about the OM-1, its small body, huge viewfinder and excellent Zuiko lenses, and adds one of the smartest automatic exposure systems of the 1970s. For photographers who want a compact SLR that can shoot in aperture priority as well as full manual, it is one of the best classic cameras you can buy.
We test and sell a steady supply of OM-2 and OM-2N cameras at Camera Collector. Here is what they do well, what to check, and how they compare with their siblings.
Quick verdict
- Best for: photographers who want an OM-1-sized SLR with reliable aperture-priority automation and full manual control.
- Strengths: clever off-the-film metering, very long automatic exposures, compact body, bright viewfinder, superb Zuiko lenses.
- Watch out for: the camera needs batteries to operate, electronic faults are harder to repair than on the OM-1, and prism desilvering affects some examples.
- Price guide (October 2026): tested OM-2 and OM-2N outfits with a Zuiko 50mm f/1.8 in our stock range from about £210 to £270, most around £215–£240.
What the OM-2 is
Olympus launched the OM-2 in 1975 as the automatic partner to the mechanical OM-1. Externally the two look almost identical, but the OM-2 has an electronically controlled shutter and an aperture-priority mode: you set the aperture on the lens, and the camera sets the shutter speed. A switch on the top plate selects auto, manual or off.
The updated OM-2N arrived in 1979 with improvements to flash operation and viewfinder information. In everyday use the two handle very similarly, and both are excellent buys.
Off-the-film metering explained
The OM-2's big innovation is OTF, or off-the-film, metering. In automatic mode, the camera measures light reflected from the film itself while the shutter is open, and closes the shutter when the exposure is complete. If the light changes during a long exposure, the camera adapts in real time.
This has two practical benefits. First, the OM-2 can make very long automatic exposures in dim light, which is excellent for night scenes and interiors on a tripod. Second, with compatible Olympus T-series flash units, it can control flash exposure through the lens, which was very advanced for its time.
Key specifications
- Format: 35mm film SLR
- Lens mount: Olympus OM bayonet
- Exposure modes: aperture-priority automatic and manual
- Metering: off-the-film in auto mode, centre-weighted
- Shutter: electronically controlled cloth focal-plane, top speed 1/1000 second
- Power: two LR44 or SR44 cells
- Viewfinder: large and bright, with a needle showing shutter speed
Handling
If you have used an OM-1, you will feel at home immediately. The shutter-speed ring sits around the lens mount, the aperture ring is at the front of the lens, and the viewfinder is one of the best of any 35mm SLR. In auto mode, a needle in the finder shows the speed the camera has chosen, so you can see when you are dropping into handheld-shake territory.
The shutter is quiet and smooth. The body is light enough to carry all day, especially with the compact Zuiko 50mm f/1.8.
OM-2 versus OM-2 Spot/Program
Do not confuse the OM-2 and OM-2N with the later OM-2 Spot/Program (often called the OM-2SP). Despite the name, it is a different camera from the 1980s with a program mode and spot metering in manual. It is a good camera in its own right and usually a little cheaper, but it handles differently and does not have the classic OM-2 needle display. Our listings always state which model you are buying.
Common faults and what to check
- Batteries and contacts: the OM-2 needs power to work properly. Clean contacts and fresh cells solve many apparent faults.
- Switch it off: leaving the camera switched on drains the batteries. Check the mode switch moves positively.
- Auto exposure: long auto exposures in dim light should time correctly and close the shutter.
- Prism desilvering: like the OM-1, ageing foam can damage the prism. Look for dark lines in the viewfinder.
- Electronic faults: erratic behaviour or a shutter that stays open can indicate an electronic problem, which is more involved to repair than mechanical faults.
- Light seals and mirror foam: commonly perished on unserviced bodies.

Alternatives to consider
If you want a camera that works without batteries, the Olympus OM-1 is the mechanical version. If budget matters most, the Olympus OM-10 offers aperture priority for less money, though it lacks the OM-2's build and metering sophistication. Outside Olympus, the Canon A-1 offers more exposure modes in a larger body.
Verdict
The Olympus OM-2 is one of the most complete classic SLRs: small, beautifully made, with a superb viewfinder and a genuinely clever automatic mode. Its reliance on batteries and electronics is the trade-off, so buy a tested example. If you want an OM-1 that can also think for itself, this is the camera.
