Photographer who want to expand focal length without buying new lenses. Teleconverter is a appropriate choice because...

• It's cheaper.
• Teleconverter lens is more lightweight than super telephoto lens.

Another consideration point about teleconverter lens.

• Optical quality is less than or not equal super telephoto lens (compare at equivalent focal length).
• Photo from teleconverter lens is darker and require more light.

For Canon

These are dedicated APO teleconverters that can be mounted between select lenses and the camera body to increase the focal length by the power of 1.4x. The new multi layer coating reduces flare and ghost, which is a common problem with digital cameras. They demonstrate best performance with DG series lenses. They also offer maximum photography magnification by 1.4 x, without any variation in the minimum focusing distance. Compact and lightweight, these teleconverters convert your lenses into longer focal-length lenses, so you don't have to do a lot of unnecessary footwork.
