The Sigma APO Teleconverter 1.4x EX DG. Mounts for
Canon, Minolta and Sony.
Pentax Digital Sigma, 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.
Extend the reach of your telephoto lens with this APO Teleconverter 1.4x EX DG from Sigma for Nikon F-mount cameras and lenses. This model will increase the focal length by about 40% while only losing 1 stop of light in the process. It also retains communication between the lens and camera, allowing users to use automatic metering and autofocus. Additionally, this teleconverter has a multi-layer coating that reduces flare and ghosting for sharp, clear imagery.
