Review Excerpt

Phenomenal resolution and detail; Great high ISO performance; Rugged, weather-sealed body; Huge, bright viewfinder; Fast autofocus works well in low light; Swift performance for a medium-format camera; Good battery life; Shoots Full HD video
Quite bulky compared to an APS-C or full-frame DSLR; Autofocus points clustered near center of frame; Most lenses aren't weather-sealed or optimized for digital; Prone to aliasing artifacts (but so are most high-end cameras these days); Attracts a lot of attention from passers-by
Read our Pentax 645Z Review

Superb build quality; Amazing EVF; Great image quality from RAW files; Good high ISO performance; Very good dynamic range; Very low shutter lag; Fast AF on stationary objects; Class-leading ~11 fps burst mode; 4K DCI and UHD video; Full HD up to 120p. Built-in Wi-Fi and GPS; Dual card slots; Decent battery life for its class.
Big for a full-frame mirrorless camera; Very slow buffer clearing; Contrast-detect AF system struggles with moving subjects; In-camera JPEGs are muted and dull; Very limited native lens selection (but supports many other Leica lenses via adapters); Expensive.
