The LA-100W is a lens adapter that lets you attach Sony α (alpha) DSLR lenses to HVR-Z7U and HVR-S270U HDV camcorders. With varying sensor sizes between the HVR-Z7U and HVR-S270U and DSLR cameras, the effective focal length of still camera lenses is multiplied by x7 when used with camcorders. This feature is perfect for shooting video of wildlife. What's more, the shallow depth of field created by the still lens is ideal for filmmaking on a budget.
