Ricoh Theta S: Ricoh pioneered the 360-degree category with its Theta line of cameras in 2013. Ricoh’s newest entrant, the Theta S, is the market leader, producing fully spherical 360-degree stills and HD videos that capture the entirety of a scene surrounding the user. Compact enough to fit in a pocket or purse, the camera has a proprietary, ultra-small, twin-lens folded-optical system that delivers bright, high quality 14MP stills and full HD spherical videos. The spherical images can be uploaded to theta360.com, shared via Facebook, Twitter and Tumblr, posted to Google Maps, Google+ and YouTube, live-streamed to a laptop or viewed on VR headsets. The Ricoh Theta S app for smartphones and tablets makes it easy to remotely control the camera, configure settings and instantly view spherical photos and video. Suggested retail price is $349.
