Review Excerpt

  • Exceptionally detailed and uniquely beautiful image quality at low ISOs; Fast, sharp 28mm-equivalent lens; Simple, straightforward controls match camera's simple, straightforward (street photography) goals.

  • Fixed-focal-length lens; Image quality deteriorates significantly at ISO 800 and above; Overall sluggish performer; Falls short when capturing JPEGs; Terrible VGA-only video quality; Very poor battery life; No built-in flash.

  • 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.
