Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter

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.

[...] give my Canon EF70-300 mounted on Canon T2i for wildlife.Works great in high light situations.Must use manual focus in low light situations.Camera shake in magnified, use a tripod if possibleIf you understand the limitations it is an inexpensive way to get more zoom.

After reading fews review for this product ,I decided to buy it couple weeks ago .. I tried with my canon 135mm f2 ... The result are really fabulous ... The image still sharp as can be .. I think even It does make ur lens lose 1 stop ... It's not really big different ... Love the sharpness of 135 f2 ^_^
It's great product to who doesnt want to buy expensive long range lens
Recently I did some test ... I use this teleconverter + extension tube + 135mm f2
Result , one nice makro lens ... I so pleased with the kenko product they look pretty nice ... N not that expensive like canon product
I love my kenko ^_^

I purchased the teleconverter to use for bird photography with the new Canon 70-300 L Lens. So far it is performing as I had hoped.

Agreat way to increase the capacity of my 70-300 Tamron zoom. Clarity is superb, greater than expected and a very reasonable way to get that longer zoom.

I have used the telegonverter on my full frame Canon D5 with Tamron 11-18mm and 18-200mm and it worked well.These lenses are for Cannon 30D.
There is a slight decrease of sharpness.
I also used it with my Canon EF 70-300mm f/4-5,6L IS USM Telephoto lens, and it was great.

Great to extend range. Works well on all my lenses, Canon and non-Canon

I got the Teleplus pro 300 DG 1.4 AF teleconverter to use with my Canon 70-300 IS lens. The photos came out great and much sharper than I expected. Mostly landscape and wildlife photos.

I have tried 2 lenses with this and thought it would give me greater range to bring in the long shots. May have to go a different direction. there are no instructions on how to use to get best pictures.

I get good quality from this TC. I was hoping to avoid the "tape trick" with this one, but be advised that this model will block AF on an F5.6 lens. It is not dust/weather sealed like the Canon TC's. I have to fiddle with my 400mm f5.6L to attach to it. Aside from that I am pleased with the output of this lens.

I use this with a EF 70-300 f/4-5.6 IS USM and with good light you can get great pictures for a fraction of the cost of a 400mm lens.

I'm a novice photographer, I recently purchased a Canon 100-400mm IS F4-F5.6 lens for My Canon T1i camera (also purchased at B&H) IMO this Teleconverter by Kenko is a great match, auto focus works, no problems. I heard about this product through a good friend, I'm glad I bought it.

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

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.

Cheaper than Canon's TC but works great. I tried it on my Canon bodies 40D and 7D DSLRs with Canon 70-300mm f/4-5.6 IS USM and the Sigma 120-400mm f/4.5-5.6 APO OS HSM. Good, firm fit with both lenses and AF working well with both. The teleconverter indeed gives that extra reach but images get soft at the far end of focal length in low light. But that's expected. The Teleplus PRO 300 DG 1.4x will not work with EF-S Canon mount lenses.

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

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!

Used in conjunction with a Canon T1i and a 100-400 L len shutter set at 125. F-stop ranged from f8 to f20 as the morning light changed. Tripod was used. Shots were at or near the max of 400. All pictures were extremely sharp.

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

Combined with a Canon 15mm fisheye inside a Seacam 4" Fisheye Macro Port, I wanted the 15mm Canon to behave like a 15-20mm and have both a sharp center and corners/edges. In fact, only the center one-third of the image was sharp, so this combo is a failure.

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

The DGX version of this teleconverter doesn't work on Rebel XTs/350Ds. I got "Error 99" messages whenever I tried to use it with a 70 - 200 f/4 lens with the image stabilizer turned on.
