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

  • Read our Ricoh Theta S Express Review

  • Superbly-built, comfortable and compact body; Pairs beautifully with pancake kit lens; Excellent image quality; Excellent performance in most respects; Great single-shot autofocus; Really nice viewfinder and touch-screen display; Friendlier user interface courts amateurs.

  • Some controls are a bit small and tightly-packed; Hand grips are still a bit modestly-sized for larger lenses; Continuous and video autofocus just isn't up to snuff; New user interface can feel limiting to advanced photographers; Underwhelming battery life.
