Review Excerpt

  • Enthusiast-oriented compact camera body; Good image quality in most situations; Impressive Dual Pixel CMOS AF; Very good overall performance.

  • Dynamic range and high ISO image quality aren't quite up to par with some of its competition; No 4K video recording; Video features in general are underwhelming; Native EF-M lens selection is limited.

  • Fantastic image quality; Improved dynamic range over its predecessor; Very good high ISO performance; Much improved real-world AF performance; Class-leading burst rates, even with RAW; Improved 5-axis in-body image stabilization; Better 4K video quality; 1080/120fps video; Dual card slots; Significantly better battery life.

  • Expensive; Menus still confusing; UHS-II support only on one card slot; No optical low-pass filter means greater risk of moire; No built-in flash; Buffer clearing still slow despite UHS-II support.
