Kenko Tele Plus MC7 2. 0X DGX Teleconverter
- Nikon Mount. The Kenko Tele Plus MC7 AF 2. 0X DGX Teleconverter also known as a tele-extender gives you the dramatic effect of doubling the focal length of your lens by 2x & will cut back the amount of light by 4x 2 fstops. The MC7 features a 7-element 4-group design with multi-coated lens elements & fully automatic diaphragm coupling. With the Kenko Tele Plus MC7 DGX your prime lens depth of field is reduced by 12 but retains the prime minimum focusing distance. Using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f 2. 8 will now be f 5. 6. The MC7 AF 2. 0X DGX converter has genuine Gated Array IC Integrated Circuitry. This means that not only the converters own unique data but all data sent from the camera body provides full exposure metering & linkage for electronic flash photography. Teleconverters are not recommended for lenses wider than 50mm e. g. 28-105mm. However full AF operation is only possible with lenses with open aperture of f 2. 8 or brighter. Please be aware that AF will work properly only if there is enough light & 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. The DGX Tele Plus converters have updated circuitry to record exif data more accurately. In the exif exposure data meta-data recorded with a digital picture DGX converters record the equivalent aperture & focal length of the lens setting plus teleconverter. Optically & mechanically they are identical to the prior high-quality DG series converters.
