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

Compact camera body; Very good touchscreen display; Excellent image quality for its class; Good overall performance.
Not many improvements compared to its predecessor, with some downgrades; No 4K video recording.
