Ricoh Theta 360
The Ricoh Theta 360 is a small (3.3 oz., 1.6 x 5.0 x 0.9 in.) digital camera with two lenses, one on either side of the camera, so that it can take 360-degree spherical photos.
To take a picture of your surroundings, just press the shutter button. If the camera is at an angle, the Theta will automatically adjust the orientation of your photo. You can also set the Theta on a table or a tripod and take pictures remotely -- and then view and/or share them -- with its iOS app.
However, if you want higher resolution results, it's better to use the desktop app (for Mac or Windows); it's also the best way to keep your firmware updated.
