Third-party reviews

What we like about OM System OM-1

  • Excellent portability due to compact camera body and lenses
  • Highly effective in-body image stabilization (IBIS)
  • Improved autofocus performance with subject detection (birds, animals, etc.)
  • Rugged, weather-sealed construction suitable for harsh conditions
  • Fast stacked sensor allows for high-speed shooting and improved noise control
  • Useful computational photography features like live ND
  • 10-bit video recording provides good image quality

What we don't like about OM System OM-1

  • Small autofocus joystick can be challenging to operate
  • Tracking autofocus is less effective than subject detection
  • No battery charger included in the box
  • Complex menu system can be difficult to navigate
  • Log video recording requires manual color space adjustment for proper skin tones
  • Smaller micro four-thirds sensor is a trade-off for absolute image quality compared to full-frame

Verdict

The OM System OM-1 is a flagship mirrorless camera featuring a 20.4MP Quad Pixel Stacked BSI Live MOS sensor and the TruePic X processor, delivering exceptional speed with blackout-free burst shooting up to 50 fps with continuous AF or 120 fps with fixed AF. Its standout characteristics include a world-first IP53 weather-sealing rating, highly effective 5-axis in-body image stabilisation offering up to 8 stops of compensation, and a class-leading 5.76M-dot OLED viewfinder. Main pros highlight its compact, rugged build, advanced computational photography modes like Live ND64 and handheld high-res (50MP), and vastly improved autofocus with AI subject detection for birds, animals, and vehicles. However, cons include a relatively low 20MP native resolution compared to full-frame rivals, occasional struggles with sticky autofocus tracking in complex scenes, and a fragile micro HDMI port that can be problematic for professional video workflows.
