Kenko Teleplus Converters

A teleconverter will effectively increase the focal length of any lens with which it is used. The KENKO Teleplus 1.4x MC DGX converter has the effect of multiplying the focal length of your lens by 1.4x. Using the teleconverter with a 300mm lens will effectively increase the focal length to 420mm. If your using the converter on an APSc DSLR (ie Canon 500D, Nikon D3000 etc) then a 300mm will effectively be a massive 672mm! All functions will remain and if the lens is f4.5 of brighter, you will also retain autofocus.
