Review Excerpt

  • 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.

  • Comfortable ergonomics and solid build; Versatile EVF and tilt-swivel, touch-screen LCD; Good image quality; Great performance for its class; New C-RAW format saves on raw file size; 4K video is an M-series first.

  • Somewhat limited dynamic range; JPEGs a little soft at base ISO, and more so at higher ISOs; Warm white balance under incandescent light; Poor battery life; Raw buffer is still shallow (but C-RAW helps).
