Overview
KENKO Teleplus Pro 300 DGX converters are made with precision quality multi-coated optical glass supplied by Hoya Corporation, the worlds largest manufacturer of optical glass. These glass elements were designed to match the optical quality of the prime lens (even at the edges) and telephoto zoom lenses. The optical design of the elements and light path is wide enough not to cause vignetting.
The PRO 300 family are designed specifically to be used with prime telephoto lenses of 100mm or above, such as 300 mm f/2.8 lenses, and work best with telephoto lenses of 200mm to 500mm. The PRO 300 can be used with telephoto zoom lenses as well as prime lenses. However, Kenko does not recommend them for zoom lenses that have a range starting under 50 mm.
KENKO PRO 300 AF Teleplus converters have genuine Gate Array IC (Integrated Circuitry). It means that the converter’s own unique circuitry maintains signal integrity between the camera body and lens. These converters are designed to electronically operate the same way as an original manufacturer’s converter.1
Full AF operation with PRO 300 2.0x DGX is possible when using camera lenses with maximum aperture 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 is required when using lenses with smaller maximum 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 tele-converter. Optically and mechanically they are the identical to the prior high-quality DG series converters.
1. Most Canon EOS camera bodies are programmed to shut down auto focus if the calculated effective aperture for the lens and teleconverter is smaller than f/5.6, the Kenko Teleplus PRO 300 converters work the same way.

Teleconverter TC-1401 is only compatible with the Global Vision lenses listed above.
*1 It becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.01 or later.
*2 It becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.02 or later.
*3 It becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.03 or later.
*4 When SIGMA TELE CONVERTER TC-1401 is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF. In cases where contrast or brightness level of the shooting object is low, it may not focus properly.
Please be advised that the updated version of lens firmware will make it compatible with the new tele converters, however it will also make it incompatible with conventional APO TELE CONVERTER 1.4x EX DG and APO TELE CONVERTER 2x EX DG.
