The Olympus OM-10 is often the first film SLR people buy, and there is a good reason for that. It is small, light, simple to operate and it uses the same excellent Zuiko lenses as Olympus's professional OM cameras. It is also one of the most affordable ways into a proper interchangeable-lens film system.
We see more OM-10s than almost any other SLR at Camera Collector, so we know its strengths and its weak points well. Here is our honest review.
Quick verdict
- Best for: beginners, students and anyone who wants an easy automatic film SLR with access to great lenses.
- Strengths: compact body, reliable aperture-priority automation, bright viewfinder, huge choice of Zuiko lenses.
- Watch out for: manual shutter speeds need the separate Manual Adapter, the camera depends on batteries, and old light seals often need replacing.
- Price guide (October 2026): in our stock, tested OM-10 outfits with a lens mostly sit between about £130 and £170, with serviced kits and extra lenses costing more. Bodies on their own are much cheaper.
What the OM-10 is
Launched in 1979, the OM-10 was Olympus's entry-level model in the OM system. It took the compact body style that made the OM-1 famous and added electronic, automatic exposure for people who did not want to think about shutter speeds. You choose the aperture on the lens, and the camera selects a matching shutter speed. This is called aperture priority, and it remains one of the most useful exposure modes in photography.
Because it uses the standard OM bayonet mount, the OM-10 accepts the full range of Olympus Zuiko lenses, from wide angles to telephotos, as well as many third-party lenses.

The Manual Adapter explained
This is the most important thing to understand before buying an OM-10. Out of the box, the camera has no shutter-speed dial. Olympus sold a small Manual Adapter that plugs into a socket on the front of the body, beside the lens mount. With it fitted and switched to manual, you can choose shutter speeds yourself and use the viewfinder display as a guide.
Without the adapter, the OM-10 is still a perfectly good automatic camera, and many people never miss manual mode. But if you want to learn exposure properly, look for a kit that includes the adapter, as they are small and frequently lost. Our listings state clearly whether one is included.
Handling
The OM-10 is light and well balanced, especially with a compact 50mm lens. The viewfinder is bright and large for a camera of this size, which makes manual focusing easier than many people expect. The shutter is quieter than most SLRs of the era.
Controls are straightforward: a mode switch on the top, a film-speed dial, and the aperture ring on the lens. Because Olympus put the aperture ring at the front of most Zuiko lenses, it takes a little getting used to if you have used other brands.
Image quality
Image quality depends on the lens, and this is where the OM-10 shines. The Zuiko 50mm f/1.8 is sharp, light and inexpensive, and the wider Zuiko 28mm and longer 135mm lenses are also very good. Metering is reliable with negative film in typical conditions, and aperture priority makes it easy to control depth of field.
Common faults and what to check
- Batteries and contacts: the OM-10 needs power to operate the shutter. Corroded contacts can cause the camera to lock up or behave erratically.
- Mirror locking up: a shutter that fires but leaves the mirror up is often a power problem, but it can also indicate an electronic fault.
- Light seals and mirror foam: original foam often turns sticky or crumbly. It is a routine fix, but it needs doing to avoid light leaks.
- Viewfinder LEDs: check that the shutter-speed scale lights up and responds to changes in light.
- Manual Adapter: if supplied, check that it clicks firmly into place and that the speeds change.
- Lens: inspect for haze, fungus and oily aperture blades. Our guide to inspecting pre-owned lenses covers the details.
Alternatives to consider
If you want a fully mechanical camera that works without batteries, the Olympus OM-1 is the classic choice, though it costs more. The Pentax K1000 offers fully manual control in a simple, rugged body. If you prefer a camera with full program automation, the Canon AE-1 Program is another popular starter SLR.
Verdict
The Olympus OM-10 is still one of the best-value ways to start shooting film with an SLR. It is easy to use, pleasant to carry and backed by a superb lens system. Its reliance on batteries and the separate Manual Adapter are the main compromises. Buy a tested example with fresh seals, ideally with the adapter included, and it will give years of enjoyable shooting.
