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
