  • Amateur Photographer

    The OM System OM-1 Mark II is a subtle evolution of the OM-1, which is already an impressive high-speed camera. This Mark II is even better – and graduated Live ND is a unique feature!

  • Compact, light, but fast and tough, the OM-1 Mark II is an excellent all-rounder. Given its tough exterior, weather resistance and svelte form factor, it could be the ideal outdoors camera, from wildlife to landscape to hiking and beyond.

    The OM-1 Mark II ups the ante in delivering plenty of bang for our buck in a body that, while chunky and weighty when compared with alternatives from the same manufacturer, really comes into its own for portability.

    In my opinion, this is the ultimate outdoor camera: it's astonishingly weather-proofed, its compactness is unparalleled, it negates the need for both ND filters and grads, it matches full frame sensors for ISO noise and actually beats them for dynamic range, the improved [...]

  • Pocket-lint 8/10

    The OM System OM-1 Mark II is one of the most capable cameras I've used, but I've seen other $2,400 cameras produce better photographs. The OM-1 Mark II's features make it one of the best Micro Four Thirds bodies available.

  • Jimmy Cheng (RED35)

    No camera is perfect for every photographer in the world, but OM System has directly addressed some of the criticisms on the original OM-1 with the brand new Mark II. As a result, it becomes the most complete photo-centric Micro Four Thirds camera to date.

    There's nothing like the OM-1 Mark II for hand-held computational photography, other than the almost identical original OM-1.
