The SAL14TC and SAL20TC teleconverters are a great way to extend your telephoto
range without having to carry more large lenses. The SAL14TC provides a 1.4x
increase in focal length with a 1-stop light loss, so when used with the SAL300F28G, for
example, you have the equivalent of a 420mm lens with a maximum aperture of F4.
The SAL20TC doubles focal length with a 2-stop light loss, so the same SAL300F28G
lens becomes a 600mm super-telephoto with a maximum aperture of F5.6. For sports,
wildlife and landscapes, the SAL14TC and SAL20TC teleconverters can give you
maximum reach with minimum gear to carry.

Carl Zeiss AG, founded in 1846, is a legend in the field
of camera optics. The company was responsible for
many of the innovations that have raised the quality of
photographic imaging to the high standard we enjoy
today, and is revered for its unswerving dedication to
delivering nothing less than the best. Sony is proud
and honored to be working with Carl Zeiss AG on the
development and production of top-class lenses for Sony
series cameras. In fact, these are the only autofocus
Carl Zeiss lenses currently available for use on digital single-
lens reflex cameras, meaning that Sony camera users have
exclusive access to legendary image quality that many
consider to be the ultimate in photographic expression.
