Canon EF 17-40mm f/4.0L USM

The Canon EF 17-40mm f/4.0L USM is a wide angle zoom lens. Its build quality makes it highly resistant to moisture and dust. This makes the EF 17-40mm f/4.0L USM a good choice if you are looking for a lens to use in challenging environments. Canon have also used lead free glass in its construction making this a more environmentally friendly lens.

One difference between this lens and many others is the fact the front of the lens does not rotate. This makes the use of filters such as polarisers and graduates more straight forward.

The inclusion of a ultrasonic motor (USM) helps to ensure faster focusing times.
