Review Excerpt

  • Extremely compact and lightweight for a DSLR; Delivers good image quality that's virtually identical to the Canon T4i/T5i; Accurate and relatively fast autofocus with improved Live View and Movie Hybrid CMOS II AF; Full 1080p HD movie recording; Better-than average kit lens (EF-S 18-55mm f/3.5-5.6 IS STM).

  • Still not as compact as most mirrorless cameras; Slightly worse than average dynamic range and high ISO performance; Poor battery life.

  • New 24MP sensor offers excellent image quality; Outstanding high ISO performance and dynamic range; Improved JPEG colors; Improved build quality; Fast autofocus; Excellent 4K video; Very good battery life.

  • Buffer clearing can be slow even with fast UHS-II cards; UHS-II support only on one card slot; No losslessly compressed RAW option; Dedicated battery charger not included; Menus are still confusing; No built-in flash.
