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.

Note: Not for Use with EF-S Lenses

    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.

      This Kenko Teleplus extends the reach of my 150-500mm lens making it even more suitable for surfing, and wildlife photography.
      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.

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

              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.

                            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.

                                I have used this with my Canon 70-200 f/4 L and Tamron SP 90mm f/2.8 Di Macro VC. In both cases I used the lenses as normal. Of course I lost one stop of light but I knew that. Auto focus worked on both lenses. I even put it on an old 28-70 f/3.5-4.5 II and it works.

                                  I use this teleconverter with my Cannon EOS xsi and 70-300mm lens. It seems to work fine when I take the time to be sure that the focus is precise. It works with my 70-300 lens, but I cannot fit it to my kit lens. It takes time to attach the teleconverter and lens when I am walking around and need to change out from my basic lens. I also found that if I leave it on AF it drains the battery. I like the reach it gives and the clarity of images.

                                    almost no loss of sharpness, very easy to mount and use.
                                    I use it with a Sigma 150-500mm, so at the 500mm end camera cannot autofocus, no big deal, I use it mostly outdoors and to take pictures of the moon at night.

                                      I use this with a Canon 70-300mm lens. It really makes a huge difference when photographing a distant object. Auto focus works most of the time. Sometimes you have to manually focus initially, but once the camera "finds" the object, the auto-focus will still work even with the teleconverter.

                                      Used with Canon 70D and 400mm 5.6 prime , for birds. Quick focus for BIF with 1 spot focus. Extremely satisfied with IQ, no difference with Canon 1.4 for image, but I get a few bonuses: AF and I save 250$. No brainer.

                                          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.

                                          I purchased this teleconverter to use with my Nikon 70-300 AF-S lens on my Nikon D300 camera. I also have a Nikon D5300 camera which I use with a 18-140 kit lens. I found that it works great on the D5300 but not so great on the D300. Auto focus searches way too much for me and I had difficulty getting it to lock in on small things like birds etc, whereas it did that just fine on the D5300. I'm returning it.
