Review Excerpt

Excellent image quality; Very good dynamic range & high ISO performance; Fantastic C-AF performance; Incredible burst rates, even with RAW; 4K UHD & Cinema 4K (DCI) video; Clean HDMI; Dual SD card slots.
Expensive; Menus still confusing; UHS-II support only on one card slot; No optical low-pass filter means greater risk of moire; No built-in flash.
Read our Olympus E-M1 II Review

Excellent build and comfortable handling; Bright, roomy viewfinder and articulated LCD; Great image quality; Good performance for the class; In-camera stabilization, GPS and Wi-Fi; Incredibly feature-rich design.
Bulkier than APS-C DSLRs; Top ISOs are for the spec sheet, not the real world; JPEGs are a bit punchy by default; Slow startup; Below-average battery life; Only a relatively modest update to the K-1.
