3D World is a camera maker based in Hangzhou, China. Its exact name is Hangzhou 3D World Photographic Equipment Co. Ltd.

Since 2006 it made the 3D World TL 120-1 Tri-lens Stereo Camera, a modern triple lens reflex camera with pentaprism TLR finder for type 120 film rolls. For some reason its dome with ocular and pentaprism is removable, perhaps to attach a simple hood instead for old-school waist-level reflex photography. It is quite heavy (2kg) and equipped with quality lenses with, thus probably intended as professional stereo camera. 2008 there may have been little improvements. Its equipped a little bit like an SLR: pentaprism dome, small thumb lever on top for film advance, combined settings wheel for film and shutter speed on top, and also a hot shoe on top. Of course that's possible since a triple lens reflex camera's finder just needs half of the camera top side.
