Wildlife and bird photography
The OM-3 has phase-detect AF with bird recognition, shoots at 120fps in pre-capture, and is sealed to IP53. At 414g it is lighter than the OM-1 series, which makes it easier to carry for long days in the field with a telephoto lens. Full guide →
Travel photography
At 414g with IP53 sealing and 7-stop IBIS, the OM-3 is a practical outdoor travel body. Light enough to carry all day and sealed enough to use in rain without concern. It pairs well with compact primes for a discreet kit. Full guide →
Street photography
Compact and quiet. The electronic shutter is completely silent and the body is small enough to avoid drawing attention. Phase-detect AF and subject recognition handle candid situations. The 7-stop IBIS extends usable ISO in low-light street conditions. Full guide →
