Our Verdict
OM System OM-1 Mark II is the wildlife photographer's camera. 120fps burst rate, AI bird detection and IP53 weather sealing in a system where 300mm f/4 gives 600mm full-frame equivalent reach. Canon R6 Mark II and Sony A9 III match or exceed individual specs — OM-1 Mark II wins for birding and wildlife where Micro 4/3 telephoto reach, weather sealing and burst speed combine uniquely.
