Sony VPL VW70 Lens Throw
The VPL-VW70 lens is a motorized, 1.6:1 zoom lens. According to the user manual lens allows the projector to be placed as close as 10 feet, 1 inch, or as far back as 16 feet 4 inches. Note, that the user manual itself contradicts itself, at one point indicating that the furthest as 15 feet, four inches which is a typo. The moderate throw range in full telephoto (16 feet four inches), is less than many other shelf mountable projectors, which, for the same sized screen can be as far back from a 100 inch screen as 20 feet. Some owners will not be able to place the Sony far enough back in their rooms to be shelf mountable.
VPL-VW70 Anamorphic Lens
The Sony VW70 does support an anamorphic lens and motorized sled, for those wanting to go with a 2.35:1 (Cinemascope) shaped screen. This is one of those extra features that Sony has put on the VPL-VW70 to differentiate it from the lower cost VPL-HW10.
