1.4x Teleconverter, 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 new multi layer coating reduces flare and ghost, which is a common problem
with digital cameras. They demonstrate best performance with DG series lenses.
They also offer maximum photography magnification by 1.4 x, without any
variation in the minimum focusing distance.
Compact and lightweight, these teleconverters convert your lenses into longer
focal-length lenses, so you don't have to do a lot of unnecessary footwork.
