Questions & Answers

JONATHAN R : Will this teleconverter work with the Nikon D3100 and Nikon 55-300mm zoom?GEORGE D : Hi there Jonathan, I have no idea if it will work for that particular camera or lens, but I can tell you this. It is a surprisingly good teleconverter. I did a lens test comparing it with a Nikon 2X Teleconverter, and it is just as sharp. The lens elements are clear, clean, and well secured. I am using it with a manual 16mm cine film lens so it will enable the image to fill the frame of my Nikon D2X DSLR, and it does a beautiful job. It works very, very well for me and my purposes. I suggest you buy this Kenko Teleconverter, try it with your camera and lens, if it does not work, return it. Adorama is a great company to deal with and will accept the return with no problems. Take care. .GARTH G : Jonathon I am using the 3x converter on a Nikon D50 and using a 80-300mm telephoto lens. The Teleconverter works very well. I am under the understanding that this Teleconverter will work on all Nikon AF camera's.

Great

Since Kenko announced to discontinue this (at least in Japan. They told me there is no plan to produce new version in Japan)and there was no stock in my country's noted ship, I bought this from Adorama as a backup. With good (but expensive) lens and supporting item (or high ISO), this teleconvertor produce amazing images for cheap 3X Teleconvertor, of course, only if you must be good at MF. Results depend on master lens, for example, it is not so impressive with DX camera and 80-200mm 2.8D New. AF of AF-I, AF-S, and Sigma HSM are killed by this teleconvertor, it is pity.

Looking Very Promising

I read nothing but horrific and negative reviews about this product but decided to try it out as an alternative to purchasing an expensive telephoto lens [...]. Almost all of the reviews I read stated that this product is unusable because the loss of light is so great when using a 3X teleconverter. I've been using this teleconverter with a Nikon D90 and 70-300VR lens. After some experimentation, I've found that you can get some excellent results by doing the following: Use a tripod to avoid camera shake, set the camera on "shooting delay mode" (option d10), use a 2 second delay self timer to eliminate further camera shake, manually focus, and use shutter priority mode choosing a shutter speed of 1/100 to 1/320 with an ISO of 800-1600 (avoiding the use of 3200 ISO to eliminate noise). Despite total suggestion to not do so, I've even gotten very good results handheld and zoomed in 100% when holding steady. This is not the purchase for someone who wants to capture a crystal clear image of a bird swooping through the sky, but still or slow moving objects can be shot with very very good results when decent lighting is available, and I'm sure that these results could be made to be considered exceptional with the addition of photoshop adjustments(of which I do not have). I can't imagine the results that could be obtained when using this product with a faster 2.8 lens (I've been using it on the 70-300VR which is 4.5 open). In conclusion, the claim that this product is useless and unusable is totally false, but this item must be used by someone willing to experiment and adjust. People who like to simply point and shoot will be disappointed.

Works as expected

This teleconverter works great. I used it with my Nikon AF-S 55-200mm 5.6 VR lens and handheld a shot with the VR on while bobbing up and down on a sailboat on Lake Erie. Remarkably crisp shot with minimum post processing. I bought it for night photography, but I'm already finding this a multi-use adapter.

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
