Olympus OM-D E-M1X

20MP Four Thirds sensor | 5-axis image stabilization | 4K video capture

What we like:

  • Up to 18 fps burst shooting with continuous AF
  • Capable autofocus
  • Excellent build and weather sealing
  • Very good in-body image stabilization

What we don't:

  • Little image quality benefit over cheaper E-M1 II
  • Menus and customization can be overwhelming
  • Comparatively large for its sensor size
  • AF tracking lags behind best-in-class
The E-M1X is Olympus's pro sports camera, featuring fast burst shooting, sophisticated AF and a substantial twin-grip design. It's currently Olympus' most advanced and most powerful camera, but image quality is similar to many less expensive options already on the market.
The E-M1X has a large number of direct controls but also provides extensive customization of buttons and how they behave. The magnesium alloy body is rated to IPX1 standard: a higher level of endurance than most cameras. In common with other professional or advanced cameras on the market, we think users can expect a bit of a learning curve and a time investment to get the camera set up the way they prefer.
The E-M1X is the best camera in the Micro Four Thirds system for fast-moving subjects
Continuous autofocus performance is good, but doesn’t quite match the very high mark set by other pro sports cameras. Still, subject tracking is impressively sticky and the mode that detects cars, planes and trains works largely as promised. The camera operates swiftly, with short boot-up times and instant response to your inputs. Battery life appears solid, which we'd expect given the two high-capacity batteries.
The E-M1X is built around a similar sensor to the E-M1 Mark II and offers comparable image quality. The new hand-held high-res mode combines multiple exposures to offer at least 50MP images (there's also a tripod mode). The Four Thirds sensor means the images will be noisier than its larger-sensor peers but will have more depth-of-field at any given f-number.
The E-M1X shoots good-quality DCI 4K/24p but never quite achieves its advertised bitrate, leading to some motion artifacts. It also offers Log shooting and 8-bit 4:2:2 output, but its other 4K modes are more modest. Despite the fast sensor and processing there's no 60p option, but the camera's stabilization is very impressive. AF tracking performance in video is also very good.
Despite its modestly sized sensor, the E-M1X is the largest - and likely best-built - Micro Four Thirds camera on the market today. It is also one of the swiftest to shoot and operate, but for a camera geared toward pro photographers shooting sports, action and wildlife, it falls slightly behind the competition in terms of AF-C performance.
