Vivitar Series 1 70-210mm QDOS 3D Lens, Minolta MD Fit. A unique, single lens 3D system based on a Vivitar Series 1 70-210mm f2.8-4 macro focusing zoom lens. Easily switches from a normal zoom lens to one that produces red/blue 3D anaglyph images with either colour negative or slide film. Results viewed with 3D glasses included. Fitting for Minolta MD film cameras, but can be used with digital cameras by adding an appropriate mount adapter. As new and unused, slight internal damage to internal packaging (from display?)
