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.
