What We Like
+Ultra-compact and lightweight (370g body-only) with IP53 weather sealing for reliable outdoor use and travel
+Class-leading 5-axis in-body image stabilization providing up to 7.5 EV compensation for sharp handheld shots and smooth video
+Dedicated computational photography button for easy access to High-Res Shot, Live ND, Focus Stacking, and other creative tools
+Intuitive updated menu system inherited from OM-1 Mark II for faster navigation and easier control

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
