I have tried this teleconvertor on a Sigma 18-50 f2.8, a Tamron 70-300 f4-5.6, a Nikkor 28-80 f3.3-5.6 and even a Nikkor 35mm prime f1.8. In all cases it functioned properly posting correct adjusted EXif data for aperture and zoom. Images suffered little to no degradation, distortion of aberration. Sharp focus and good AF performance, even zoomed to 300mm @ f5.6, though it was a little slow at that point. I am delighted with the new range this gives my lenses. At this price ($140) it was a steal!

Bought primarily for use with EF70-300L, which won't accept Canon TC's. I use it with other lenses and my telescopes also. Very pleased.

Using this on an EOS T6i with a legacy 70-200mm f5.6 lens (full frame, from a film body). Autofocus works--- must of the time, but sometimes becomes difficult at longer focal lengths. Not sure why; it doesn't seem to be a function of ambient light. Manual focus isn't always a bad thing. I didn't experience the switched-off battery drain mentioned by others--- I've made a point of leaving the teleconverter installed for several days. No effect on the battery. The lens stays sharp all the way out at the 200mm setting. For the money, I'm pleased.

If you are trying to extend a good-quality Nikon lens such as the 200-500 or 70-300 then my experience is you will not be satisfied with this extender; at least I wasn't. I did detailed pixel-peeping comparisons of raw images of rock grain shot with a D7200 with those two lenses with and without this extender, and in both cases the cropped images without the extender had slightly better detail. Admittedly the loss isn't much, but if I can do better without the extender than with it I don't see the point. If you put this on a telephoto that isn't razor sharp then you might not notice the loss, but with these two lenses the loss was obvious.

Excellent image quality when used with the AF-S Nikkor 300mm f/4D. See samples. Build quality is quite good. As noted by others it results in overexposures on both the D750 and D7000 requiring a 1.3 to 1.7 stop compensation. And it severely overexposes with the AF screw drive lens I tried it on. But for my intended use, I find it to be an excellent investment.

This Kenko works great with my Canon L lens collection. Auto focus and lens/photograph information is also captured corrected with the image. I have found no downside with this teleconverter and find it more capable than the Canon OEM for about 1/3 the cost. Recommended.

A small light teleconverter . I satisfied.

I needed this to attach Canon 100mm f2.8 for professional work. The CAnon adapters would not allow me to attach my macro. This worked without a hitch.

Purchased the Kenko Teleplus Pro 300 DGX 1.4 to use with my Nikon 200-500 5.6 VR lens, making it a 280-700 F8 lens, plus on my Nikon D500 1.5 factor, making it a 35mm equivalent of a 420-1050mm lens. All of the data contacts are there with the TC, so nothing was lost, all electronics work as expected. Would recommend for anyone trying to get a little extra reach and at a 1/3 of the Nikon one, its a bargain.

I'm very impressed with this converter, especially for an inexpensive 3rd party piece. I bought this primarily to give my 'walkabout' lens (24-120 f/4) some extra reach when I don't want to carry an additional longer lens. On a D610, with this extender, the 24-120 still focuses fast and accurate, even in very dim light, VR works, it reports the adjusted efl and f#, and it provides more resolution than switching to DX mode or cropping... Just what I wanted! No, its not Nikon build quality, but I wasn't expecting that at the pricepoint.

I bought this about a year ago. I like the lens. It works well and resolution appears good. I use it on my Canon 7d typically mated to my Canon 24-105 zoom. Great versatility. So its a good lense. The problem I have encountered is that it totally drains the camera battery when the camera is in the off position and this lense is attached for a few days. It took some investigation on my part to isolate this 1.4 extender as the root cause of the battery draining. I did not think it was possible with the camera shut totally off. So i do not leave this lense on the camera anymore when idle for a few days. If i do, out of convenience I remove my battery.

Allows me to use a DX lens on my D750 with virtually no vignetting. The trade off is losing 2 stops

[Retired] Because of different reviews, I decided to do my own tests, trying to keep it as fair as possible.. Cameras; Nikon D750 and a Nikon D500, Lenses; Nikon 24-85F4.5 & 70-300F5.6 FX[full frame] , 18-55F5.6 & 55-30F5.6 DX[3/4 Frame], also 25 year old Tokina ATX film lenses 28-70 F2.8 & 150-500 F5.6[All Manual].. This is what I found; I shot Colored Stone, Trees, Airplanes.. Checking for Sharpness & overall Clarity.. I found the standered 1 stop loss with the 1.4 & Very very little Loss of sharpness & Clarity, For some Oddball reason my 18-55DX lens would not work Correctly, it's auto-focus kept jumping around.. All other lenses, auto-focus worked decent, as you still have to have enough light coming in to work the focus sensor.. I found that on the 300mm [W/the 1.4] it was better to use manual focus on anything other than Full sunlight.. In my case, with the 1.4 mounted, everything else worked just fine.. Oh, I also mixed the FX & DX lenses between the Full frame and 3/4 frame Cameras.. Have Fun Photographing..

Tried this with a Nikon 70 - 200 2.8 lens. Shot wild elk in a field. Could only get about 30 yards but this converter managed to grab a clean shots. Was able to crop the original image considerably to get a magnificently clear and very usable cropped final image. With this lens would recommend shooting between 5.6 - 8 for clean edges.

This extender works well with my Canon 70-300L lens and Rebel camera body. It allows me to keep my pack as light as possible but still have the reach I need for animal photography. I received it a few days after ordering. I am very happy with my purchase.

I was trying this with a 70-300 zoom lens. I found that most but not all of my photos were soft. The AF worked if the camera was steadied on a monopod and the subject didn't move. If there was motion as any part of the equation, it hunted. Because f8 was its limit, it hunted in anything but bright sun. MF works okay. Just not a good combination for my purpose, birds, so I'm returning it.

I like it. Works pretty good. Image quality is better than the old converters I used in the film days. Fit is a little loose and I lost communication with the lens a couple of times shooting a football game, especially when I went vertical. A little jiggle and communications came back. Shortcoming but a good solution for gaining reach and worth 1 stop trade off.

This teleconverter is being used in conjunction with a Nikon 180mm f/2.8 lens and with a 72mm f/6 telescope for astrophotography. I have been getting crisp images with no apparent loss of resolution compared to the 180mm lens alone. It works well with the telescope also.

This converter works perfectly with my Nikon equipment, including a variety of lenses. Image quality is first rate and the auto focus is exceptional, especially with prime lenses.

The quality of the pictures has more to do with the lens you mount this on. I use it on a Canon ef 70-200 f/4 with very good to excellent results. The limiting factor is in obtaining precise focus as the depth of field is reduced with higher focal length. Also on the Canon 85 f/1.8 at f/2.8 with great sharpness. There is some color fringing on the 85mm but that is characteristic of the lens not the converter. The connection between lens and converter is not lock tight, but presents no meaningful problem. There is very little to complain about with this product. It just works well.

I am still comparing images with this teleconverter. One thing is for sure, it saves money on buying even more expensive glass. I use this TC with my 70-300L, and so far, the images have been acceptable. My 420mm shots are not as clean as my 300mm shots, but I have 120mm more reach than I had before.

DONALD R.

2014-02-11T19:00:00

Use it with my 100-400L. It does not seem to degrade the image at all. It does cause my 7D to hunt with the lens unless there is high contrast and lots of it. Lots of light is needed also to get AF. BIF do not seem possible.

After dealing with Nikon tech support (equivalent to no support) I bought a Nikon teleconverter which was incompatible with my lenses. This was after spending much time with Nikon tech & having them tell me that the lenses were compatible. I sent the Nikon back & bought the Kenko which solved my problems, is a quality product and is easy to use. I recommend it.

HARRY S.

2013-07-15T21:00:00

I use it with a Canon 70-300. It does the job.

Gives me that extra reach with very little degradation in image quality.

2012-06-03T21:00:00

I use this mostly with my 90mm Macro and it kicks it out to 126mm for closer shots. Easy to carry and works great. Very happy.

I use this T.C. with several Canon lenses and it just works! AF is fast and accurate. Picture quality is excellent while using this T.C.! Another advantage is the T.C. reports all information to the camera body, so one knows all photo specific details. I like to know my focal distance when I review my photos. One thing I would like Kenko to include is: maybe there can be an asterisk somewhere on the file, so one knows when a T.C. was used, but not at max focal length. Maybe it's an Adobe or Apple issue? If an identifier already exists, then disregard my comment. It's my ignorance for not figuring it out!

Used with Canon 7D, Canon EF 70-300mm f/4-5.6 IS USM. With typical landscapes and good light, the Kenko TC performs very well, focusing quickly with good accuracy. I noted some softening at the extremes, but that was expected and somewhat correctable in software. Much better than expected performance shooting macro from 5 1/2'. Birds in flight presented a much larger challenge and performance here was inconsistent with focus often too slow to capture subjects accurately. Overall, a useful addition to the bag for Canon shooters wishing to extend their range a bit without taking out a second mortgage for "L" lenses and the pricey Canon TC that only works on "L" lenses. The Kenko TC will NOT work on EF-S lenses and in some situations, count on focusing manually for best results.
