20.4MP Live MOS Sensor. The Olympus OM-D E-M1 Mark II offers continuous RAW shooting at 60 fps when working with the silent shutter and single-shot autofocus, and up to 18 fps using continuous autofocus. With the mechanical shutter, you can reach up to 15 fps with single-shot AF. The TruePic VIII image processor allows ISO ranges all the way up to 25,600.

4K Video. 4K video comes in both flavors, 17:9 DCI and 16:9 UHD. DCI records at a true 24.00p with a super-high 237 Mbps bit-rate, while UHD is available at 24p or 30 and 102 Mbps. There’s a built-in stereo mic to capture scratch audio, or you can use the 3.5mm external mic jack to record. There’s even a headphone jack included so you can monitor everything.

Pro Capture. Pro Capture is basically a buffering system for stills. With a half-press of the shutter button, the EM1 II starts taking full resolution JPEGs or RAW images. A full button press saves the current image and the previous fourteen frames.

Dual F.A.S.T. Autofocus System. The lightning-quick Dual F.A.S.T. autofocus system combines 121 contrast-detection points and 121 phase-detection points. The 121 phase-detection points are cross-type more precise tracking in poorly lit conditions and better subject tracking capabilities.

Stable Image. The five-axis sensor-shift image stabilization system accounts for 5.5 stops of shake in basically all directions, keeping your image rock solid when you’re shooting handheld.

Built-In Wi-Fi. The Wi-Fi system offers simple connection to smartphones and tablets. This allows you to view and download images to the device, as well as make camera exposure and focus adjustments on the device while shooting.

Design and Features. For framing and composition, there’s a 2.36m-dot electronic viewfinder and a 1.04m back rear LCD. The body is magnesium alloy, making it light and strong. It’s weather sealed and good in the cold down to 14°F. Images and videos are recorded to SDXC cards in dual slots, but do note only slot 1 supports UHS-II cards. There’s a new battery this time around, the BLH-1, that’s rated for up to 440 shots per charge.
