    Kenko K1.4PRO300DGX-N reviews

    Teleplus PRO 300 DGX 1.4x AF Teleconverter is rated 4.2 out of 5 by 103.
    Rated 5 out of 5 by from Great Product I recently purchased a Nikon D7100 and a Nikon AF-S 300mm f/4D ED-IF Lens and I wanted to use a 1.4x teleconverter with that combination for bird and wildlife photography. After a lot of research and comparison, I decided to go with a Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter rather than the significantly more expensive Nikon offering. I'm glad that I made that decision. The Kenko performs flawlessly. AF is fast, metering is accurate, and image quality exceeds my expectations. Comparison of photos taken both with and without the teleconverter show no significant image degradation or lack of sharpness. The teleconverter mounts very smoothly to both the lens and the camera. I am very pleased

    Rated 5 out of 5 by from Kenko PRO 300 DGX 1.4x Great with Nikkor 200-500mm f/5.6 Bought the Kenko PRO 300 DGX 1.4x to add to Nikkor 200-500mm f/5.6 which extended it to 700mm. I am very surprised at the image quality I'm getting from this combo. I was actually expecting it to be as good as it is. Quality is almost as good as the Nikkor 200-500mm f/5.6. It does drop the f/stop down to f/8 but if you have good light images are sharp and clear. The Kenko PRO 300 DGX 1.4x also reports correct f/stop and zoom range to camera body, and on my D750 zoom fine tune knows when its being used. Great addition if you're looking to extend the lens range. I have also tested it on a few of my other lens those results are a little mixed but on the Nikkor 200-500mm f/5.6 it is a well worth purchase.

    Rated 4 out of 5 by from Works without issue with my Nikon and Sigma lenses The product appears to be quality built. Contrary to the Nikon Teleconverters, which only work for selected Nikon Lenses, the Kenko Teleplus Pro 300 1.4x teleconverter works with all my Nikon lenses as well as my Sigma 150-500. Even with the Sigma 150-500, I don't find autofocus is an issue as long as there are sufficient lights. With enough light, I was able to autofocus with the Sigma 150-500 even with an effective aperture of 9 when the lens is fully zoomed out. And, I can't notice any visible degradation to picture quality neither. That being said, I think the autofocus is slightly slower than that without the teleconverter. So, all in all, it works.

    Rated 5 out of 5 by from WOW After reading many reviews for the Nikon 80-400 AF VR 4.5-5.6 lens I was concerned that a photo-multiplier would not work with it, or at least not well. When I went to purchace my lens on the B&H website there was a section for accessories I might be interested in. The Teleprus PRO 300 DGX 1.4 AF was on the list. I read the reviews and decided that for the price it was worth the risk to try. I have been amazed at how well it works. Although as with all teleconverters you lose a few f-stops, the thing really works. I have used it sparingly in the few weeks I have owned it, but it has performed beyond my expectations.

    Rated 5 out of 5 by from Great teleconverter! I have used the Kenko pro 300 1.4x teleconverter for a few weeks now on several outings with both my Nikon 18-200 and 70-300 on a D7000 body. I can see no noticeable degradation. Obviously, you lose a couple stops, but the images are crisp from edge to edge. I was happy to get the Kenko as the Nikon teleconverter will not work on either of these lenses. I have yet to try it on my primes, but I really wanted it for the zooms as I am about to take just one body and the two lenses on an Alaskan cruise. It is solidly built and works as well as Nikon teleconverters I have used in the past.

    Rated 4 out of 5 by from Very useful. Used this on a Nikon D750 with several different lenses, nikkor, 300mm f4 pf & 28-300mm f 3.5-5.6 and Sigma 150-500mm f5-6.3. Unlike the Nikon TC which can't be used with the 28-300 the elements on the DGX do not extend past the mount face and so can be used with lenses like the 28-300. It reports the f and focal length to the camera, and AF and VR both work (on the 300mm PF there is a loud noise when VR is working but it does work), it also autofocuses on the sigma when zoomed giving a combined f of 9 when AF is supposed to stop working at f 8. Images were good and AF is fast enough for sports and birds in flight.

    Rated 2 out of 5 by from Did not work with 80-200mm f/2.8D ED AF I purchased this teleconverter for my Nikkor 80-200mm f/2.8D ED AF zoom lens on my d700 after reading reviews of how well it worked with this lens for sport photography. My 80-200mm is tack sharp, dead on pretty much all the time even when tracking animals and birds at high speed. With the teleconverter, I was totally dismayed at how soft the images were and there was loss of color depth. I tried shooting stopped at multiple apertures, but not too tight so as to avoid lens diffraction and I still had trouble. I did not try to fine tune the AF for this lens combination and maybe I should have though.

    Rated 4 out of 5 by from Huge benefits on long and short lenses. This is the only teleconverter available for the Nikon D700 that permits the focus and VR to work. The Nikon versions do not. Fortunately this lack of choice did not result in any lack of satisfaction on my part. Bought the Kenko teleconverter for my 80-400 mm VR Nikon lens to improve my chances of getting decent shots at Bosque del Apache. The results have been outstanding. I can finally fill up my viewfinder with clear, sharp images. Also, I had not anticipated that I would get such great benefit using the 1.4 teleconverter with my 24-120 mm and 14-24 mm lenses. The teleconverter has not been off my camera since I purchased it. Except for occasional close up work it is starting to look like a good device for keeping dust out of my camera body.
