Kenko TelePlus MC4 AF 2.0X DGX Teleconverter for Sony A
Key Features
  • For Use with Sony A-Mount Cameras
  • Multicoated Lens Elements
  • Integrated Circuitry
  • Doubles Focal Length of Lens
The Sony A-mount Kenko TelePlus MC4 AF 2.0X DGX Teleconverter effectively doubles the focal length of your lens for greater reach. The MC4 features a 4-element, 4-group design with multicoated lens elements, and fully automatic diaphragm coupling. With the Kenko TelePlus MC4 DGX your prime lens' depth of field is reduced by 1/2, 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.

Kenko MC4 Overview

The Sony A-mount Kenko TelePlus MC4 AF 2.0X DGX Teleconverter effectively doubles the focal length of your lens for greater reach. The MC4 features a 4-element, 4-group design with multicoated lens elements, and fully automatic diaphragm coupling. With the Kenko TelePlus MC4 DGX your prime lens' depth of field is reduced by 1/2, 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 MC4 AF 2.0X DGX converter has genuine Gated Array IC (Integrated Circuitry). This means that not only the converter's own unique data but all data sent from the camera body provides full exposure metering and 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 and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.

The DGX TelePlus 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 and focal length of the lens setting plus teleconverter. Optically and mechanically they are identical to the prior high-quality DG series converters.
