Vivitar's 1.4x Teleconverter for Sony adds another valuable tool to your camera bag, at a very affordable price. This compact and lightweight 1.4x teleconverter multiplies the focal length of any compatible lens by 1.4--a 100mm lens with this teleconverter attached, for instance, would give you the view of a 140mm lens. The multi-coating on the converter reduces flare and ghosting, common problems with digital cameras. And, the minimum focusing distance is unchanged. This teleconverter comes with a lifetime warranty.
