Details

 

Kenko's TelePlus MC4 AF 2x Auto Focus 4-Element Teleconverter (also known as a tele-extender) for Nikon doubles the focal length of your lens while retaining the prime minimum focusing distance. Depth of field is decreased by 1/2. MC4 denotes a 4-element, 4-group design featuring multi-coated lens elements. It has a fully automatic diaphragm coupling. Using a 2x teleconverter with (for example) a 300mm lens gives an effective focal length of 600mm. With this teleconverter a lens set to f/2.8 will now be f/5.6.
 
The TelePlus series of converters has Gated Array Integrated Circuitry. This permits the signal between prime lens and camera body to continue unimpeded, meaning that autofocus will function correctly where lenses have an aperture of f/4 or brighter. Lenses with lower f/stop values it may be necessary to focus manually. This circuitry also provides more accurate recording of meta-data. 

  • For Use with Nikon Digital SLRs
  • Lens Elements are Multi-Coated 
  • Proprietary Integrated Circuitry
  • Focal Length of Lens is Doubled 

IMPORTANT: Teleconverters are not recommended for lenses larger than 50mm (for example 28-105mm, 75mm etc). Full AF operation can only be realized with lenses of open aperture f/2.8 or brighter. Autofocus will only work correctly if there is sufficient light and contrast on the subject to trigger the camera's AF sensors. For smaller f-stop values, manual focusing is recommended.
