Description:
KENKO Teleplus Pro 300 converters are made with high quality multicoated
optical glass supplied by Hoya corporation, the worlds largest manufacturer of
optical glass. This glass will match the optical quality of the prime lens (even
at the edges, unlike many teleconverters on the market today). The optical
design of the elements and light path is wide enough not to cause any
vignetting.They are designed specifically to be use with telephoto lenses of
100mm or above, and work best with telephoto lenses of 200mm to 500mm. The PRO
300's can be used with telephoto zoom lenses as well as prime lenses, but, due
to their design, Kenko does not recommend them for lenses that have a zoom range
that starts under 50 mm.Kenko PRO 300 converters are intended to be used with
expensive telephoto lenses and larger camera bodies. They have all metal lens
mounts in both front and rear, as well as a metal core, to support today's heavy
professional camera bodies.Kenko PRO 300 AF teleconverter will not auto focus
with the following Nikon lenses: Nikon AF-S ED 300mm f/2.8D (IF), Nikon AF-I ED
400mm f/2.8D (IF), Nikon AF-S ED 500mm f/4D (IF), Nikon AF-S ED 600mm f/4D (IF),
Nikon AF-S ED 80-200mm f/2.8 (IF), Nikon AF-D ED 200mm f/4. DG Series New
DG Series have upgraded "Gated-Array" circuitry to work better with the digital
SLR's and some of the the new digital only lenses. They still work the same with
film SLR Cameras and lenses as well.
