I have had this product for 3 ½ years and reviewed it about 3 years ago…I have more to add regarding compatibility between cameras and lenses, image quality, and build quality…all the things we look for from a user's review.

First, of course, you will lose one f/stop, but only one…unlike the 2X and 3X teleconverters, where you will lose two and three f/stops.

I have used this teleconverter with my Canon 5D2 and my 400D (Rebel XTi) camera bodies. It worked flawlessly on both cameras with the following lenses: the Canon 50mm f/1.4 USM AF, Canon 70-200L f/4 USM, Canon 24-105 f/4L IS USM, Tokina SD 11-16 f/2.8 (IF) DX, Tamron AF 17-50 f/2.8 XR DiII SP, and the Sigma 150 f/2.8 APO Macro DG HSM…with and without my Speedlites (580EXII, 430EX, and 220EX).

Regarding lens and camera body compatibility issues with the Tokina and the Tamron lenses: Both lenses were designed to be used with APS-C sensor cameras, like my 400D. They were not designed for the 5D2, which has a full-sized sensor. The Tamron is worthless on the 5D2 due to severe vignetting, and with the exception of the 16mm zoom setting, the Tokina is likewise unusable once the zoom is opened up toward the 11mm wide end (it actually works fine at 16mm). However, with the addition of the 1.4X teleconverter, both Tamron and Tokina work with little or no vignetting (very slight vignetting at both lenses' widest opening…an easy fix-it task with PhotoShop). Note: Obviously neither of these lenses are made by Canon, which may account for the fact that although they are EF-S mount lenses, they still work with the Kenko teleconverter.

Of course, the teleconverter's 1.4X magnification power factor has a similar effect as Canon's cropped APS-C sensor cameras in that the relative magnification power is increased; so an 11-16 zoom actually becomes a 16-22 wide zoom, and so on. But that's still less than the 1.6X factor increase from an APS-C sensor…the same 11-16 effectively becomes an 18-26 wide zoom. The bottom line here is that the teleconverter has allowed me (if I choose to) to use two more lenses (dedicated APS-C sensor lenses) on my 5D2 that I was unable to use without the teleconverter.

Connectivity issues: Although the Kenko teleconverter allows the two camera bodies to "talk" to all of the above-mentioned lenses flawlessly (that includes aperture, shutter speed, AF, and IS), I have one lens that will not talk to either camera body through the Kenko connection pins. My ProOptik 8mm f/3.5 Fisheye lens works OK on my 400D (in its quirky prehistoric way), but not correctly on the 5D2 (it's vignetting above and beyond the Nth degree). Neither camera, however, recognizes the ProOptik's connectivity when the Kenko is added to the mix, resulting in "error" messages.

Image quality does not appear degraded by this product…at least as far as I can see. Although I've mentioned the vignetting issue, the color fringing (chromatic aberration) is also affected by the teleconverter in a positive way. Since color fringing is generally more pronounced with wide angle lenses and at the wider end of wide zooms, the 1.4X magnification reduces the "wide" and consequently it appears to reduce the color fringing at the contrasty edges. At least that's been my experience.

Finally, the Kenko Pro 1.4X teleconverter has a nice, professional finish. The connection to my camera bodies was clean, tight, and solid; and it disconnects cleanly.

I used this with a 60D and 70-300 IS 4-5.6. I would say the photos I tested with were a little bit sharper at 100% crop compared to 140% crop without it. I found that the images look great if you know how to use your camera and to make adjustments accordingly. In AV or TV mode they we're a little over exposed and blown out. By compensating by stepping down the EV -2/3 the images were great.

True I often used manual focus and my lens became a 5.6-8 aperature as expected. No problem as I expected this.

The reason I gave this 3 stars is because of the build quality/design. The front protector cap on it was very loose and was expecting it to fall off in the camera bag. If the ap comes off and scratches the element it may be destroyed?

More alarming was the truth that my lens detached from the TC on 3 or 4 separate occurances. I think my fingers touched the release button while zooming and the whole lens twisted off. Two reasons I think this happened is that the button protrudes unnecessarily far from the body and the spring that holds the lenses together is really not strong enough. I ser no reason why the buttonis not flush with the TC body. I tested the spring of the body and I feel it really was kind of flimsy. I would rather not use this product than drop and damage a lens.

Fails to render clear pictures

By Eric

Comments about Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter:

Within the past year, I have purchased a Canon 5DS R and a Cannon 70 - 200mm L/4 lens. In addition to these two purchases, I purchased the Kenko Teleplus Pro DGX 1.4x AF Teleconverter to increase the range on this Canon L lens for bird and wildlife photography. This Canon L lens on its own renders beautifully clear pictures on both the Canon 5DS R and Canon 6D. Very impressed with this L Lens performance on its own.

Having said that, I mounted the above Kenko teleconverter to the Canon L Lens and tested the lens on both Canon cameras. After 7 separate shooting events over a 30 day period, the performance of Kenko teleconverter is a real disappointment when it comes to rendering clear images in both autofocus and manual focusing. With the use of this teleconverter, the clarity of the images has degraded and the beautiful pictures I was once receiving with the Canon L lens on its own is now a dream of the past. The testing included test shots using high and low ISO, apertures, and shutter speed (1,000+). Therefore, camera shake was not the creator of the problem on the Canon 5DS R. Remember, similar tests were performed on the Canon 6D.

Even though I have shot over 100,000+ photos over the past 10 years, I consider myself a highly trained semi-professional photographer. I shoot for the art of photography.

What good is it to increase your overall focal length on a lens by 1.4x if it is only going to degrade the quality/clarity of the photo you were once receiving without it?

Sorry Kenko, but the user of this product gives this teleconverter a failing (F) grade.

I bought this for my 400mm and I am happy with it so far. It gives me extra reach and fuller frame for the birds. Better than crope it.

      Purchased the Kenko PRO 300 DGX 1.4x teleconverter to use with a new Canon 7DMII and EF-100-400 L II. Unfortunately, it gave an error with this combination (Lens FW Upgrade required). Also tried it on a Canon 5DS-R with EF 100-400 L I and got the "Lost Communications with Lens" error. It worked fine with the two Canon 6D's and both lenses. Returned to B and H with no hassle and now have a Canon 1.4 on the way. I can recommend this item IF your camera/lens combo supports it.

        Comments about Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter:

        I already have the PRO DG version since a couple of years. Everything works perfecly but without correct EXIF data (not seen by the camera body).So I ordered the DGX. Try several thing like removing the battery. Not working ERR... most of the time. I send an email to KENKO and here is apart of the reply:Concerning Canon 70-200 f.8 mm L IS II

        Please refer to Teleplus compatibility chart

        For this lens no restrictions but please check the following precautions on the first page

        Turn off all image correcting functions before using Kenko TELEPLUS DGX. The image may become extremely dark or bright.

        Turn "Power saving" mode off before using Kenko TELEPLUS DGX

        VR (Vibration Reduction) function may or may not work. To avoid problems with VR, turn this mode OFF

        Please, turn off the following functions and modes in your camera: aberration correction function, focus aid assistance mode.

        Secondly, your camera is not in the list of Canon cameras that are confirmed complete work with Kenko Teleplus.

        So I ask for a RMA and got it easily from B&H. I will now continue to use The Canon 2X extender EF III purchase from B&H. An excellent one by the way...

          On its first outing it appears to produce a very good image with the lens racked out to its limit.

              I have tried to compare pictures taken with and without Teleplus PRO 300 DGX 1.4x AF Teleconverter by Kenko when using my 300mm lens, and found no apparent benefit. This likely is due to reduced aperture because of this product added.

                  I bought this TC about 2 years ago and I use it on and off for bird and wildlife photography on Canon 7D with Sigma 120-400mm lens. With this teleconverter I find the picture quality rather poor: a bit grainy and soft. Specially at the far end of focal length. But for that low price I accept that sometimes it's better to have any photo at all than to have none when the subject is too far out in the distance. Even if the quality is compromized.
                  Some reviews here indicate that people have had good results with this teleconverted. Unfortunately, I cannot say the same.
                  I think, my next purchase will be new proprietary Canon 2x TC. No more 3rd party stuff.

                        This teleconverter is very sharp when used with a crop sensor camera. I can barely tell the difference in sharpness between having a teleconverter and not having one. It is less sharp when used with a full frame camera. It is lighter than the canon teleconverter because it is has a plastic casing. It sends lens exif data to the camera when used with a canon lens, but may not with a non-canon lens. Unlike canon teleconverters, this teleconverter works well with wide-angle lenses.

                            As per my previous review of this product it works great on my Canon 6D. I just tried it on a 7DMKII with a 200mm f2.8 lens and it locks up the camera. The proper aperture shows but no auto focus ( not even an attempt to focus ). The battery has to be removed to unlock the camera. Too bad. Looks like I'll have to purchase the Canon teleconverter.

                                Autofocus works good with this combo. Product feels solid and well made but the caps look cheap plastic.
                                Big price difference for the canon model.
                                Worth it!!

                                I like the extra reach it provides. Still getting used to how to shoot with it as it tends to over expose. Comping down by -1/3 seems to help.Yes a little loss of IQ but for the extra reach to get out to ducks, I can live with it. Also a little play in the lock up to the camera body, but otherwise a nice addition to have.

                                  I use the older DG version of this lens on the Canon 100-400L. To be honest I wasn't expecting it to be that good but the images are barely distinguishable between using the converter and not, so I've had excellent results with it. No problems focusing either but I had to tape the first three pins for auto focus. When using the converter the EXIF information is not correct, at least not with the pins taped.
