I bought this teleconverter to give me more reach when trying to shoot birds in flight. I am using it with a Canon 60D and EF 200 F2.8L. So far, I have used this teleconverter a handful of times to take pictures of ducks in water in good light. The autofocus works okay, but the images are not as sharp as I would like and I think that I might be better off with just using the EF 200 2.8L and heavier cropping on the 18.0 MP camera. I think the autofocus with just the lens is just a bit sharper and there is less distortion before the light hits the sensor.

I bought this 2X teleconverter to add more reach for pictures of wildlife. I have a Canon 200mm f2.8 L lens that performs superb, but I needed to get birds and animals closer and I wanted to avoid spending a lot more money for another lens. Everywhere you read that the teleconverters reduce light and quality of your images, so I was somehow skeptical. After getting the Kenko 2X I have to admit that the maximum aperture becomes 5.6 instead of 2.8, but the speed of focus and quality is almost comparable to what I can achieve without it. I have been able to take incredible shots of birds and safari animals and I couldn't be happier with this.
I would definitively recommend anyone who doesn't want to spend significant amounts of money in a 400mm L class lens to get a 200mm and add this item. I also use it with a 50mm 1.8 and with a Sigma 10mm fisheye and still I get excellent shots that I wouldn't be able to get otherwise.
I also considered buying the Canon 1.4 and Canon 2X teleconverters, but be aware that you cannot use them with all lenses. They are designed to fit only very top of the line glass.
I also tried the 3X in the store and realized that you get extreme tele but it doesn't autofocus. At least with my 200mm Canon L 2.8, however if you can tolerate having to manually focus, perhaps is a good idea. I am really considering getting that one as well.

This one is replacing the 4 element that I have. I think the picture quality is much better with this one. If you have never used one of these before, I would suggest starting out with the 1.4X and working up from there. You might be suprised at the results you can get with some practice.

For someone who will use this seldomly it's okay. It grinds a little putting on the camera and the light has to be quite bright for the focus to work at all. I haven't decided yet whether it is better than just blowing up the photo in Photoshop. Not recommended for serious telephoto work.
