Update: Loreo has released the same kit for Nikon, Sony, Olympus, Panasonic and Konica-Minolta SLRs.
Loreo has released a new Stereo Lens-In-A-Cap for Canon cameras ( APS-C format subframe digital SLR sensors, 22-24mm). It costs $165. Using these kinds of lens you get one photo that has two images in it, side by side (see here for some samples from Loreo). You can view the 3D images in Loreo’s own 3D viewer, or change the photo digitally to other 3D formats.
