I wish it was white like the picture

It is a function of the Canon EOS D5 Mark II that will not autofocus with an F8 lens. Don't expect original sharpness or even 2X sharpness with a 3X extender. However, it is really nice to have a 400mm F2.8 lens go to 1200mm F8. All other lens functionality is passed through this extender.

NOT HAPPY

Had this product for about a month now. Used it at different times with different subjects. The results were the same...very bad. Very disappointed with this product.

Does the job but

The converter produces clean sharp images however it is advertised to autofocus with 2.8 or faster lenses. I have tried it with a 18-50 F2.8 sigma a 50mm F1.8 Canon and a 70-200 F2.8L Canon none of which could auto focus. If it can't autofocus with the 70-200 F2.8L it can not autofocus with anything. Rating would have been a 5 but false claim of autofocus is missleading. I learned to take pictures in the days when autofocus was not the norm but now I am spoiled and use autofocus. I do set everything else manually. I use this on a Canon 40D.

About Kenko Teleplus PRO 300 DG AF 3x Teleconverter/Canon EOS

Placed between the camera body and lens, a teleconverter contains a set of optics that will effectively increase the focal length ofa lens by a specific amount. Common magnifications are 1.4 times and 2 times, but the Kenko Teleplus PRO 300 AF converter has a 3x magnification. For example, using a 3 times (3x) teleconverter will increase the focal of 300mm lens to 900mm.

The Teleplus PRO 300 converter is made with high quality multicoated optical glass supplied by Hoya Corporation, the worlds largest manufacturer of optical glass. The PRO 300 3x is designed for use with lenses of 50mm or above and work best with telephoto lenses of 100mm to 500mm. The PRO 300 3.0x can be used with telephoto zoom lenses as well as prime lenses. However, Kenko does not recommend them for lenses that have a zoom range that starts under 50 mm.

KENKO PRO 300 AF Teleplus converters have genuine Gate Array IC (Integrated Circuitry). It means that the converter's unique circuitry maintainS signal integrity between the camera body and lens. These converters are designed to electronically operate the same way an original manufacturer's converter would provided there is enough light available.

Important Note: Due to the 3 stop light loss inherent in a 3x converter, Kenko states that the PRO 300 3.0x converter will not auto focus with lenses that have a smaller aperture than f/2.8. With all lenses having apertures smaller than f/2.8, Kenko recommends using the PRO 300 3x in manual focus mode.

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 o nly lenses. They still work the same with film SLR Cameras and lenses as well
