The PRO 300 series of Kenko Teleplus teleconverters are designed specifically to be used with telephoto lenses. They work best with prime lenses of 100mm or more and zoom lenses with a widest focal length above 50mm. The KENKO TelePlus PRO 300 AF 2.0X DGX converter has the effect of multiplying the focal length of your lens by 2.0x, turning a 300mm lens into an equivalent 600mm lens.

The PRO 300 AF 2.0X DGX converter has genuine Gate Array IC (Integrated Circuitry). It means the converter’s unique circuitry maintains signal integrity between the camera body and lens. The telephoto optimized 7-element design is made using high quality multi-coated optical glass supplied by Hoya Corporation, the world’s largest manufacturer of optical glass.

Full AF operation with the TelePlus PRO 300 AF 2.0X is possible using camera lenses with open apertures of F2.8 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 may be necessary when using lenses with smaller open f-stop values than that 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.

PRO 300 2.0X DGX are available for Canon EOS (EF, not EF-S) and Nikon AF.
