Kenko 2.0X PRO 300 Teleconverter DGX for Canon EOS Digital SLRs Reviews
| 15 of 15 people found the following review helpful  Canon Compatible Lens multiplier, By Amazon Verified Purchase This review is from: Kenko 2.0X PRO 300 Teleconverter DGX for Canon EOS Digital SLRs (Electronics) The Kenko 2.0X Pro 300 lens multiplier is a cost effective way to have a much larger lens. Kenko uses Hoya glass lenses in this product. Hoya lenses are among the best made glass lenses in the world. The different lens series made by Canon causes not all lenses to work with the 2.0X lens multiplier made by Canon. Buyers should always be mindful of compatibility when mixing and matching products for your favorite camera. For example, while I was searching for a 2.0x lens to add to my Canon lens (75-300mm) I noted that some listings on the web listed a lens multiplier with similar nomenclature information with one small difference. The difference I noted was with "DGX" Vs "DG". The "DG" lenses listed were physically different than the "DGX". The picture shown for a "DG" lens had a small metal tab with contact pins which protruded beyond the edge of the lens on the end that connects to the camera body. This metal tab is not present in the "DGX" version. This tab would not have fit...

If you're hoping to use this with a consumer grade zoom lens you may be disappointed and would probably be better off looking at a 1.4x teleconverter. These 2x teleconverters are designed to work with f2.8 lenses or faster (although I've had very good luck using it with f4 lenses)I originally purchased this teleconverter and then decided to purchase a Canon 2x II to see how they would compare. What my tests revealed was that on a crop frame camera (Rebel, 40D, 60D, 7D) and my 70-200 f2.8 lens their performance was virtually the same. I ended up selling my Canon and using this 2x Kenko. The other big advantage of this teleconverter over the Canon 2x is how it performs on f4 lenses. On my 70-200 f4 or my 300 f4 the Canon 2x would disable autofocus unless I used the "tape trick" (google it) to trick the camera into not seeing the teleconverter. The Kenko doesn't do...

I have found the picture quality to be very good with with these lenses. I am shooting with Canon xsi and t2i bodies, and both work fine with this extender. Also, camera information is retained and the changes caused by the extender are properly accounted for.One thing I've observed with my extenders is that they also magnify the softness, noise, blur from shake, etc. A lens that tends to be soft will yield unacceptably soft pictures with the extender. I tried my 1.4x extender on my Sigma 18-250, which is a soft lens, and the results were very poor. This is important to know, because I think extenders are taking the blame for the lenses in many cases. I have found that both the Kenko 1.4x and 2x DGX Pro 300 extenders work very well on high quality L-glass, and also on my Tamron 28-75 f/2.8, which is also a very... Read more |

Product Description
Kenko AF 2.0x Super High Quality Teleplus converter also has genuine Gated Array IC and is compact for light weight and easy handling. Full AF is capable with lenses having a maximum aperture of F/4.5 or brighter. (Manual focusing will be required with lenses of smaller aperture.)Placed between the camera body and lens, a teleconverter contains a set of optics that will effectively increase the focal length of a 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 2 times (2x) teleconverter will increase the focal of 300mm lens to 600mm. The Teleplus PRO 300 converters are made with high quality multi-coated optical glass supplied by Hoya Corporation, the worlds largest manufacturer of optical glass. These glass elements are 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 is designed specifically to be used with prime telephoto lenses of 100mm or above, such as, a 300 mm f/2.8 lens, 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.
