AF 2x Teleplus MC7
Placed between the camera body and lens, a teleconverter contains a set of optics that will effectively increase the focal length of any lens it is used with. The KENKO Teleplus MC 7 AF converter has the effect of doubling the focal length of your lens. For example, using the MC 7 AF teleconverter with a 300 mm lens will effectively increase the focal length to 600 mm.
It is an easy and inexpensive way to increase the abilities of your telephoto lens without the expense of purchasing and carrying another telephoto lens. Kenko Teleplus converters are small and easy to carry in your camera bag.
KENKO Teleplus MC7 AF converters are made with high quality multicoated optical glass supplied by Hoya Corporation, the worlds largest manufacturer of optical glass.
The MC 7 converter has genuine Gate Array IC (Integrated Circuitry). It means that the converters unique circuitry maintains signal integrity between the camera body and lens. These converters are designed to electronically operate the same way an original manufacturers converter would.
Full AF operation with Teleplus MC7 is possible with camera lenses with open aperture of F/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the cameras AF sensors. (Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.)
