OM System OM-1 Mark II

The OM System OM-1 Mark II is an incremental update to the brand's flagship Micro Four Thirds mirrorless camera, tailored for wildlife, action, and outdoor photographers. Powered by the TruePic X image processor and a 20.4-megapixel stacked BSI Live MOS sensor, this model maintains a highly compact form factor while introducing key hardware and system refinements. It focuses on expanding memory capacity and enhancing computational photography features over its predecessor.

Best for Wildlife and action photography requiring fast burst rates and deep buffers to cBest for Landscape photography in unpredictable weather without the burden of physical ne
Pros
  • Doubled buffer memory allows for much longer high-speed continuous shooting sequences.
  • Advanced built-in computational options, including Live ND and a new Graduated ND filter simulation.
  • Highly durable construction with IP53-certified weather sealing for reliable outdoor use.
  • Upgraded autofocus tracking capabilities and improved in-body image stabilization.
Cons
  • Highly incremental update over the original model, with few physical hardware redesigns.
  • Sensor resolution remains limited to 20.4 megapixels.
