The Sigma APO Teleconverter 1.4x EX DG for Pentax Digital SLR Cameras is a dedicated APO
teleconverter that can be mounted between select lenses and the camera body to increase the focal
length by the power of 1.4. The multi-layer coating reduces flare and ghosting, which is a common
problem with digital cameras. The lens also offers maximum magnification without any variation in the
minimum focusing distance. Compact and lightweight, this teleconverter can convert your lenses into
longer focal-length lenses, so you don't have to do a lot of unnecessary footwork. A case for the lens is
included.
