Review Excerpt

  • Excellent image quality; Good grip; Full HD video recording; Swiveling LCD; Very fast autofocus; HDMI output.

  • Slow frame rate for sports shooting; Tendency to overexpose in bright sunlight; Live View AF is slow; No microfocus adjustment.

  • Vastly improved burst speeds with deep buffer; Great performance with very fast autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; High-quality 4K video with uncompressed HDMI out; Super-fast High Frame Rate video; Same great pocket-friendly design.

  • Pricey for a compact camera; JPEGs can look over-processed at higher ISOs; Lens doesn't offer as much telephoto reach; Battery life not as good as predecessor; 24-70mm-equivalent lens can feel limiting.
