Does this teleconverter - Kenko 2.0X PRO 300 Teleconverter DGX for Canon EOS Digital SLRs - work on Canon EFS 55-250mm and EFS 18-55mm lenses?

This is an excellent teleconverter, I can make very good to excellent 11x 14 + prints without a problem. It will not with your lens, it works with the lens for a full frame camera.

I checked the compatibility sheet and this Kenko 2X PRO 300 DGX tele-converter DOES NOT support Canon EF-S lenses. Sorry...

The Kenko 2X Pro 300 DGX is not compatible with the newer "Canon EFS" lenses. The issue is that the newer lenses rear structure extends further into your "Canon SLR" when mounted than the older Canon USM lenses.

According to the manufacturer's website, it requires a minimum focal length of 100mm. So it will definitely not work on your 18-55mm, but not sure about the 55-250mm. My guess is that it will not work. Also, they claim the converter is designed for fixed focal lenses, but don't believe that is a requirement.

Well mine works perfectly with the Sigma 1.4X teleconverter and if you check the Sigma compatibility page here: http://www.sigmaphoto.com/teleconverter-compatibility, you can see it will work with the 2X. Hope this helps.

Sorry, It does not work on DX lenses, But being DX lenses your 18-105 actually has the same field of view as 27-157mm and the 55-300mm has the field of view 80-450mm due to the crop factorThese teleconverters are really only designed to work on Fast Pro Glass.. Nikon camera bodies really cant focus with apertures higher then f8.. So the lenses attached needs to be a minimum of f4 constant aperture to work properly. Here is a link to all the lenses it works with..

Have not tried it on the Canon 70-300L. Works with Tamron SP 70-300 VC, Canon 50 1.4, Sigma 50-500 OS, Sigma 70-200 2.8 OS, Canon 100 2.8L. Basically, has worked with every EF lens I tried. Does not work with EF-S. Sharpness with the Tamron 70-300 @ 300mm (420mm in total) is better than the Sigma alone at 500mm. So, it is a good teleconverter.

No, it will not, at least, not on my 350D (Rebel XT), and neither will it work for my 18-55 EF-S. The converter mounts to the camera OK, but the back of each lens has a little rubbery snout which prevents the lense from fully seating in the converter, the converter is just not deep enough...

I really don't know for sure because I don't have that lens. I use the Kenko TCs with my D700, mostly on a Nikon 300mm AF-D type lens. It would depend on whether the 28-300 has a rear element that might protrude too far into the TC while zooming to one end of the zoom range or the other. Kenko TCs have a different design and are not so fussy as Nikon's TCs which need to be paired very carefully with particular lenses. It would be good to ask someone in a camera shop or on-line photography forum, or similar source. Other than that, you'd want to check the compatibility of your camera's compatibility with the electronic connections (probably okay for most newer equipment). The nice thing about Kenko's DGX model (instead of the DG) is that it sends the proper modification of the zoom value to the camera's EXIF information.

Not the 1.4 converter, but with extension tubes. You can retain auto focus with the right extension tubes. Kenko DG Auto Extension Tube Set for the Canon EOS AF Mount works for me.

I have Sigma 150-500 for Canon. It works great with Sigma Teleconverter AF 2x DG using Canon 5D MK III, 70D, T3, and T5 with Manual Exposure or Auto without 2x.

I read somewhere it does NOT work. I would not recommend this combination anyway fr quality reasons. It is a bad idea to use a converter for a wide-to.tele-zoom. Teleconverters are best for fast lenses (2.0...4.0) and longer focal lenghts (fixed or fast pro telezooms).

You need EF mount lenses. EF-S mount lenses will not fit this teleconverter. In general, teleconverters are a bad idea unless you use them with very high quality lenses. The converter will magnify any flaws the lens already has. It would be more cost effective to buy a longer prime lens than trying to use a teleconverter on any lens with a maximium focal length less than 100mm. You would also be better off just cropping your shots from a telephoto lens that has a maximum aperture narrower than f/2.8 or f/4. Since any 2X converter doubles the effective focal length, it also increases the maximum aperture by two stops. An f/4 lens becomes an f/8 lens. An f/5.6 lens becomes an f/11 lens and so on. An inexpensive telephoto lens such as a 70-300mm f/4-5.6 becomes an effective 140-600 f/8-11. Most Canon bodies disable auto focus any time a lens or lens/converter combo with maximum aperture narrower then f/5.6 is mounted. The 1D series wil allow auto focus to function up to f/8.

I have a D3100 and the teleconverter works but it is slow to focus. If I had to buy again I would not save the money and buy a nikon teleconverter it works better and faster.

Yes it should work fine. I have the same setup on my D7100 and the results are great. Slightly more difficult to focus on small distant objects with the teleconverter attached.

Hi. The issue to keep in mind is the distance from the outer most Canon extender lens surface to the Bower telescope recessed lens in all the available lens extenders (lens magnification multipliers). In this case I have to advise not a good idea as they will not match up. I do use an extender multiplier lens adapter made by Kenko, C-AF 2X Teleplus Pro 300. I have used it with all my Canon lenses and the Bower lens you are asking about. Remember, you will also need an adapter ring to match the Bower lens to the Canon camera or extender. When ordering the Bower lens you will need to pay attention to which adapter ring is being offered as they list it with different adapter rings for sale on Amazon.com. Additionally, when looking at other than Canon lens extenders (2x) be careful with the issue of lens depth as you match one lens with an extender. The Kenko 2x lens extender does allow room for Canon lenses to fit. Hope this is helpful. If you have any other questions just use the same system to write. Without saying, putting a 2X extender on a 600 to 1300 mm lens will make it very difficult to focus on an image unless you have a really good tripod...heavy duty and expensive. One with adjusting gears will make life a lot more fun. Good Luck!!!

Since this teleconverter works with EF lenses only it will fit the 60D which is equivalent to 224-960 with the crop factor of 1.6. 70-300 x2 = 140-600 x1.6= 224-960. but at the same time the aperture will also suffer from f4 to f8 or smaller. I've used this for my 60D and to even get adequate shutter speed with the smaller aperture you have bump up your ISO by which the images then becomes grainy and doubling it with this converter makes the final image unacceptable. I don't recommend this teleconverter on an APSC sensor at the long end of a telephoto lens. I used a Tamron 28-300 telephoto with this converter and the images were horrible. If the lens isn't sharp in the first place this converter will magnify that flaw x2!

I would go to the Nikon web site... look at the teleconverter section and find this model and then go to the compatibility section for lenses it is compatible with ...... I would be leary about purchasing them (especially used).........

The teleconverter I purchased was for Canon product and would only work on certain lens types. You'll need to review the Nikon compatible teleconverter specifications and check with Nikon to determine what lenses it will work with.

I don't have this lens so I don't know for sure. Check the Nikon compatibility table at http://www.nikonusa.com/en_INC/IMG/Assets/Common-Assets/Images/Teleconverter-Compatibility/EN_Comp_chart.html
