OM System OM-1 Mark II
A standout pro Micro Four Thirds body, the OM-1 Mark II pairs a 20.4 MP stacked sensor with 8.5-stop IBIS, 4K60 video, and IP53 weather sealing in a 599 g shell. It is a wildlife and birding favorite, leveraging small MFT telephoto glass and deep computational features. Skip it for full-frame low-light or shallow-DOF looks, or maximum-resolution landscape work where 20 MP is limiting.

Verdict
Best for
- Wildlife / birding on the go — 20MP stacked sensor, 8.5-stop IBIS, IP53 weather sealing
- Telephoto reach with small, light MFT glass and deep computational features
Who should skip this
- Full-frame low-light / shallow-DOF work
- Maximum-resolution landscape (the high-res mode helps but the sensor is 20MP)
