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

  • Higher resolution and better image quality than SL1; Much improved dynamic range; Excellent Dual Pixel CMOS AF; Compact body with improved ergonomics; Articulating touchscreen; Full HD movies up to 60p; Better battery life.

  • Shallow buffer depth with RAW files; Dynamic range and high ISO performance still not as good as leading competitors; No 4K video option; OVF only offers 9 AF points.
