Worth Knowing
−No AI-based subject detection beyond faces and eyes, limiting autofocus tracking for wildlife and fast-moving subjects compared to competitors
−Same 20.4MP sensor as original OM-5 with minimal core upgrades, making it challenging to justify upgrade from previous generation
−Limited 4K video capabilities at 30p only, no 10-bit recording or log profiles for professional video work
−Micro Four Thirds system offers smaller sensor than APS-C alternatives, resulting in reduced depth-of-field control and potential high-ISO limitations for demanding scenarios

Read our notes on general
The OM System OM-5 Mark II is a refined ultracompact mirrorless camera built for outdoor enthusiasts and travelers who prioritize portability without sacrificing capability. It combines a reliable 20.4MP sensor with class-leading 5-axis stabilization, an intuitive new menu interface, and computational photography tools like Live ND and Starry Sky AF—all wrapped in a weather-sealed body weighing just 370g. While its core specs remain unchanged from the original OM-5, usability improvements like the dedicated CP button, deeper grip, and updated menu system, along with USB-C charging, make this a strong refresh for adventure photographers.
