Sony SAL-20TC 2x AF Teleconverter
Sony 2x Teleconverter for A Mount is placed between the back of most Sony G series A Mount lenses and the mount of an A Mount camera. The effective focal length is increased by 2x, or doubled. It is supported by both full frame and crop frame sensor camera bodies. Teleconverters are useful for shooting sports, wildlife, and other stadium events to give your lens more reach.
