Review Excerpt

  • Large-sensor image quality. Sharp lens with useful zoom range. Tilt/swivel LCD. Twin dials. Smaller than competing interchangeable-lens cameras with a similar lens. Lots of photographer-friendly features.

  • Not as small as you might hope. Mediocre burst shooting and autofocus speed. Far too easy to accidentally change exposure compensation. Viewfinder is of surprisingly little use. Battery life could be better.

  • 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.
