Our editorial take on the OM System OM-1
The OM System OM-1 is a flagship Micro Four Thirds mirrorless camera built for speed, durability, and computational photography. With a 20.4-megapixel stacked sensor and TruePic X processor, it delivers up to 120 fps continuous shooting, robust subject detection across nine categories (including birds, planes, and trains), and class-leading 8.5 EV stops of in-body stabilization. The body is compact at 511 grams, yet built from magnesium alloy with IP53-rated weather sealing and freezeproof operation. Video shooters get DCI 4K at 60p, 10-bit internal recording, and external RAW output, plus useful features like a live ND filter up to ND128 and vertical video support.
Reviewers praise the OM-1 as an excellent all-rounder that pairs light weight with serious capability. Its computational features, including handheld pixel-shift high-resolution mode and extensive focus bracketing (up to 999 shots), make it a strong pick for photographers who prioritize versatility and portability. The electronic viewfinder boasts 5.76 million dots, and dual UHS-II SD slots ensure reliable storage. At $2,199, it sits at the premium end of the Micro Four Thirds ecosystem, but the combination of speed, stabilization, and rugged build make it a compelling flagship for wildlife, action, and travel shooters who don't need full-frame resolution.
- Blazing 120 fps continuous shooting with 1053 phase-detect AF points
- Best-in-class 8.5 EV stops of in-body stabilization
- Compact, lightweight 511g magnesium body with IP53 weather sealing and freezeproof rating
- Extensive computational features including live ND filter (up to ND128) and handheld pixel-shift high-res mode
- Versatile subject detection for nine categories (birds, trains, planes, pets, humans, vehicles)
- Micro Four Thirds sensor is smaller than full-frame or APS-C, limiting low-light performance and depth-of-field control
- 20.4 megapixels may feel limiting for large prints or heavy cropping compared to higher-res competitors

The OM-1 looks a lot like previous Olympus cameras. The styling and overall size are basically the same. However, the OM-1 includes a new EVF ...
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.
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 ...
The OM-1 is a great choice for people who love fast frame rates, state-of-the-art computational photography like handheld Pixel-Shift high-resolution shooting.
It is bright, clear and sharp. It makes the EVF a pleasure to use and is a huge upgrade compared with the previous generation's old 2.36 million ...
