Extenders, generally known as teleconverters, increase the effective focal length of lenses. Canon Extenders are available in two strengths, 1.4x and 2x. As the names suggest, the 1.4x Extender increases the focal length of your lens by a factor of 1.4, and the 2x by a factor of 2.

Are Canon extenders worth it?

The Canon Extender 2x II works great, but it only can do so much. It really does give a much longer focal length, but with two stops less speed, while remaining pretty sharp and with very good AF performance. AF is slower, especially if it has to rack a long way in or out.

It’s as fast as the 70-200mm f/4 IS L, but a little slower than the Canon 70-200mm f/2.8 L IS II. Just grab the focus ring at any time for instant manual-focus override. Only move the AF-MF switch to MF if you want to disable the camera from auto focusing….

Does autofocus work with 1.4 x extender?

Can I stack Canon extenders?

How much does a 1.4 teleconverter do?

A 1.4x teleconverter brings a one-stop reduction in maximum aperture; a 2x teleconverter brings a two-stop reduction. So if you use a 1.4x converter on a 300mm f/4 it becomes a 420mm f/5.6. And if you use a 2x teleconverter on a 70-200mm f/2.8 it becomes a 140-400mm f/5.6.

Can I use 2 teleconverters?

Using more than two is possible, but it’s not recommended. Problems of using teleconverters are amplified. Both image quality and optical quality can suffer.
