This is a great converter

This works great. Unlike the Canon brand it works with all my lenses. The auto focus isn't great but I have been using manual focus cameras on the job for over 20 years so it isn't a big deal to me.

This is a great product

This converter works very well. I use it on a 50mm 1.4 Canon lens and it's great. I also use it on a 80-400mm.Really need a tripod for that one.Have tried handheld.Can do it up to 200mm but not past 200. I see no loss in quality with the 50mm and very little with the 80-400mm. overall a great product.

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 lenses: Canon EF 50mm f/2.5 Macro, Canon EF 100mm f/2.8 Macro, Canon EF 85mm f/1.8 USM, Canon EF 300mm f/4 IS USM.
NOT compatible with the new Canon EF-S lenses, 18-55 f/3.5-5.6, 17-85 f/4-5.6, 60 f/2.8 macro

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
