Kenko TelePlus PRO 300 AF 2.0x and 1.4x DGX
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.)
With the PRO 300 1.4x, DGX full AF operation is
possible with camera lenses having a maximum aperture of F4 or brighter.
The same light and contrast requirements apply.
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.

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.
