The OM System OM-1 is an OM System Micro Four Thirds camera released in 2022, built around an 20.4MP stacked BSI Live MOS sensor. Key features include 8-stop IBIS, phase-detection AF, subject recognition, 4K video, and weather sealing. It replaces the Olympus OM-D E-M1 III. It has been succeeded by the OM System OM-1 Mark II. At 599g, this is 61g above the M43 average of 538g, noticeable but within the expected range for a body with this feature set. The Panasonic Lumix G97 is 80g lighter if that matters.
Best for: Wildlife and sports photography
Pros
- Class-leading 8-stop IBIS
- Phase-detect AF with subject recognition
- Weather sealed to IP53

Wildlife and bird photography
The OM-1 introduced phase-detect AF and bird subject recognition to the OM System lineup. It shoots at up to 120fps in pre-capture mode. Weather sealed to IP53, the body handles field use in rain and dust. The 2x crop factor gives strong telephoto reach. Full guide →
Sports and action
Fast burst rate, reliable subject tracking, and a stacked BSI sensor that reduces rolling shutter make the OM-1 a capable sports camera. The 7.5-stop IBIS helps at slow shutter speeds for panning.
Macro photography
In-camera focus stacking is available on the OM-1, letting you shoot a bracketed sequence and merge it without leaving the camera. This is practical for field macro work with live subjects where conditions change quickly. Full guide →
