Extending a lenses focal length by a factor of 1.4x, the Canon Extender EF 1.4X III incorporates excellent optical performance with minimal chromatic aberration and is a perfect complement to many of Canon super telephoto lenses The Canon Extender EF 

The Kenko Tele Converter MC7 AF 2.0X DG Teleconverter (also known as a tele-extender) gives you the dramatic effect of doubling the focal length of your lens by 2x, and will cut back the amount of light by 4x (2 f/stops). The MC7 features a 7-element, 4-group design with multi-coated lens elements, and fully automatic diaphragm coupling. With the Kenko TelePlus MC7 DG your prime lens' depth of field is reduced by 1/2, but retains the prime minimum focusing distance. Using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. 

Designed to extend a lenses focal length by a factor of 2x, the redesigned Canon Extender EF 2X III delivers optical performance on par with the finest Canon super telephoto lenses The Canon Extender 2X III features a built-in microcomputer for seaml

The 1.4 EX is placed between the lens and the camera, and it allows the photographer to use the 70-200mm f/2.8 lens as a 98-280m f/4 lens, and the 300mm f/2.8 lens as a 420mm f/4 lens; the high optical performance is maintained and the AF speed is not aff 

The 2x EX is placed in the same way and it allows the photographer to use the 70-200mm f/2.8 lens as a 140-400mm f/5.6 telephoto zoom lens, and the 300mm f/2.8 lens as a 600mm f/5.6 ultra telephoto lens.
