The Loreo 3D Lens in a Cap (patent pending) is a new gadget for SLR cameras with interchangeable lenses. It is the latest in Loreo's digital ready Lens in a Cap series. The 3D body cap turns a standard or digital SLR into a 3D camera. SLR cameras have accurate viewing, exposure control and a wide range of shutter speeds. Some SLRs have auto TTL flash. Most can be fitted with powerful external flash units. With the Loreo 3D Lens in a Cap, these features are harnessed to produce excellent 3D prints or digital images. The processed 3D prints are ready for viewing with LOREO Deluxe or Lite 3D viewers. They can also be viewed on computer screens with a Loreo Pixi 3D Viewer. Viewing in Anaglyph format is not recommended.
For the technically minded the 3D Cap has a matched pair of focusing lenses, focusing range from one meter to infinity. F/11 lenses, focal length 38 mm. The 3D Lens in Cap is a brand new design. It forms a 3D effect by transposing two images. Beam splitters designed in the 1960s for SLR cameras have a pronounced keystone effect. The 3D Lens in a Cap retains a slight keystone effect, almost imperceptible without the use of a grid. This was introduced under controlled conditions as a compromise to give the viewfinder a brighter image and to allow the TTL exposure system to function. It is a self-contained, integrated lens and reflector system that mounts directly onto the camera body and does not need any supporting lens. This means that it does not work with SLRs which do not have interchangeable lenses, such as the Olympus E10 and E20 digital cameras. It ships with a choice from 7 common mount types - Canon EOS, FD, Nikon, Olympus, Pentax K, Minolta MD and AF. It is not available with M42 because there is no way of ensuring alignment with a screw mount, which is essential for taking good 3D pictures.
