  • 1Description

With the Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter full autofocus (AF) functioning is possible with lenses having a maximum aperture of f/4 or brighter. Having 1.4x magnification, the Teleplus PRO 300 is constructed of 5 multi-coated elements in 4 groups and allows a depth of field 1/1.4 of the prime lens used and retains the prime's minimum focusing distance.

The Teleplus PRO 300 has genuine Gate Array IC, which means that not only the converter's own data but all data sent from the camera body provide full exposure metering and electronic flash photography.

    Kenko K1.4PRO300DGX-C reviews

    Teleplus PRO 300 DGX 1.4x AF Teleconverter is rated 4.3 out of 5 by 95.
    Rated 5 out of 5 by from A great purchase! My first impressions upon opening the package were very positive; the build quality is very good, the appearance of the extender is very professional, even the packaging itself made you think you made a worthwhile purchase. I have used this so far on a Tamron 70-300 VC USD lens as well as a Canon 400mm F5.6 lens. On both lenses I find the autofocus works extremely well,and the EXIF data reflects the correct information. The image quality of my first shots with this extender is excellent. Colors are good and the clarity and resolution are great. I'm very pleased with this purchase and also pleased with the service from B&H Photo as well.

    Rated 5 out of 5 by from worked as expected on 70D with 70-300L Worked well on my 70D with Canon 70-300L lens. Focusing performance using just center point was no different with the teleconverter in the 70 - 200mm range. I did notice focus performance dropped off at 300mm, and often required multiple AF retries before focus was achieved. With a 1.6x crop sensor (70D) and 1.4x teleconverter, I was getting effective focal length of 672mm at maximum zoom with this lens. The price to performance cannot be beat and is best value. For bird and wild life photography in good light, one can spend thousands more for very little extra performance. Best value body + converter + lens combination I think.

    Rated 5 out of 5 by from Works well with 400mm f/5.6L I wrote a review earlier and have since then done some experimentation to see if I could improve the autofocus functioning. At first I couldn't get the lens to reliably autofocus. My 7D camera is set to use the center focusing point with this lens when shooting wildlife and especially birds in flight. The lens with teleconverter tries to focus under these conditions but is almost never successful. Putting the camera in zone autofocus makes all the difference. Now it works very well even in relatively poor light. It's not perfect but it gets the job done almost all of the time. I'm very happy with it and the optical quality is first rate, even when the lens is wide open.

    Rated 4 out of 5 by from The only option for EF 70-300L Got this because it's the only teleconverter option for the EF 70-300L. I've taken several hundred photos with that combination on a 7D and I can confirm that image quality does not suffer in the least. The lens is sharp as ever, even at 420mm (672mm on crop bodies). However, you do lose an aperture stop, so the 70-300L at 420mm starts at f/8. It also causes the autofocus to hunt like crazy on the 7D, even in good light. Generally, I plan on focusing manually when using the Kenko. Nice little teleconverter for the EF 70-300L.

    Rated 5 out of 5 by from Great product! I have owned this for over a year and purchased after reading reviews that the overall sharpness was better than the Canon 1.4 and 2.0 converters but have not compared them myself. I have used this converter on my 50D with EF-S 28-135mm and EF 70-200mm 2.8F IS II and saw little to NO loss in sharpness and No distortion. However, You might loose a stop or 2 in low light with the added glass. Ive used it mainly for outdoor sports in natural light. AF works good on both lenses but I have noticed my 50D has a little harder time locking on, and does hunt a little more if I push it. IMO Well worth it for the extra reach when you need it. I am very happy with my Kenko and Highly recommend!

    Rated 3 out of 5 by from noticeably soft I bought this to use with my 60D and 70-300L based on positive reviews. However, it was immediately clear that the images were downgraded compared to the lens alone, although mostly not by a lot. Cropping images taken without the TC gave results equal to or better than those with the TC, with the advantage of the extra stop and without slower focusing and sometimes hunting. Other than that it worked fine, and would appear to be very useful with a lens of lower quality than the L, where the difference would likely not be noticeable and the reach would be an advantage.

    Rated 4 out of 5 by from Works great and its inexpensive The quality of the product far exceeded my expectations considering the price. I was expecting it to look and feel cheap but that wasn't the case. With a perfect day on hand and knowing where some Egrets would be hanging out, I decided to give give this thing a go. I used the teleconverter with a Canon 70-300mm lens mated to a Canon EOS 60D. My objective was to test out the autofocus and clarity of the images on an clear and sunny day. I'm going to let the pictures do the talking for the rest of this review.

    Rated 4 out of 5 by from Image quality good but focus hunts Bought this for my 40D and 70-300L -- this puts the lens at f5.6 @ 70mm and f8 @ 300 -- so it shouldn't autofocus, but it does with the Kenko. However, it doesn't focus like the lens alone (which is incredible) -- and if it starts autofocus search it goes through the entire focus range -- may be a way to customize that esp if you have a 7D though. I used it this weekend on high powered rockets and got some real keepers mid-flight, but had to go to manual focus some times. On my 200mm f2.8L (making it a f4) the focus was very acceptable. Image quality was very good.
