Review Excerpt

  • 360-degree spherical panoramas at the click of a button; Puts you back in the moment like no other camera; Good ergonomics and control layout; Great still image quality, and can shoot videos too; Upload panoramas to Google Street View

  • Very reliant on your smartphone or tablet; Battery and storage can't be replaced or upgraded; Handheld shots suffer from Gigantic Hand Syndrome; Hard to get yourself out of the shot; Video image quality is only modest; Interval timer has a long shot delay

  • 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.
