The Canon EF 2x II Extender is the easy and cost-effective solution for those looking for a way to extend the focal length of their current Canon L Series lenses. The Canon EF 2x II Extender can multiply the focal length setting of your current lens by two.

The lens extender is relatively light and has a compact size. The build quality of the Canon Extender EF 2x II Lens Extender, like you'd expect from Canon, is excellent. It is also weather-sealed.

Do note that using the extender will not affect the Minimum Focus Distance of your current lens. This also means that the Maximum Magnification of the lens will also be multiplied by 2 times.

One other thing to note is that you should expect the quality of the image to be slightly degraded when using the 2x. You may notice the sharpness and contrast to decrease a bit. It is recommended to use Canon EF 300mm f/2.8 L IS USM Lens with the extender if you still want to achieve a sharp image.

As it is, the extender will come very handy for those looking to create a longer focal length for their current lens. Ultimately, the best feature of the Canon Extender 2x II Lens extender is its price.
