Review Excerpt

  • High quality images with lots of detail; Excellent graphical user interface is fun to use; Smart implementation of WiFi makes it relatively easy to share photos wirelessly.

  • Designed so much like a DSLR you may wonder why you shouldn't get a DSLR instead; Some performance issues, particularly slow buffer clearing and shot-to-shot speed; Initial WiFi set-up can be confusing.

  • 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
