Review Excerpt

  • Phenomenal detail and "depth" at low ISOs; Extremely high resolution; Incredible image quality for the price and size (at low ISOs); Fast x-sync speeds; Unique design is unconventional but comfortable and balanced.

  • Poor high ISO performance; Very sluggish buffer clearing; Poor low-light AF; No built-in flash; Very limited third-party RAW file support; Bundled Sigma Photo Pro RAW software is slow and buggy.

  • 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.
