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

  • Very good image quality; Good high ISO performance; Fast Dual Pixel CMOS AF autofocus system; Eye AF with tracking & video support; 4K video; Good build quality; Excellent value.

  • No IBIS; Sub-par dynamic range; Burst shooting tops out at 5fps; Poor battery life; Limited video features.
