Review Excerpt

  • Compact and lightweight for a fully-featured interchangeable-lens camera; Really fast autofocus; Good all-around performance too; Generous buffer depth; Versatile tilt/swivel LCD and high-res viewfinder; Touch-screen controls; Very affordable pricetag

  • Out of the box, colors are muted by consumer standards; Warm white balance under incandescent light; Handgrip is a little shallow for those with larger hands; Wi-Fi is overly complex and has limited range

  • 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.
