A high-quality, wide-angle zoom for a variety of subjects.

The EF 17-40mm f/4L USM is an ultra wide-angle zoom lens that offers excellent image quality and a constant maximum aperture. Its compact, lightweight body makes it an ideal travelling companion.

* Superb optical performance throughout the zoom range
* Fast autofocus speed
* Highly resistant to dust and moisture
* 28cm minimum focusing distance at all focal lengths

A fantastic option for both full-frame and APS-C photographers and videogprahers alike! The 17-40mm f4.0 allows video users especially to still capture those wider perspectives and allows for easier focus pulls. Pleasing bokeh and robust ergonomics ensures an intuitive user experience. A more budget option and alternative to the 16-35mm f2.8 lens, with a bit more on the longer end. DSLR video shooters should definitely consider this lens especially if they are shooting with Full-Frame cameras like the 5D Mark III or the Canon EOS 6D.

Ultra-wide or standard zoom
The EF 17-40mm f/4L USM acts as an ultra-wide angle zoom on film or full-frame digital EOS cameras. On DSLRs equipped with APS-C sized sensors it acts as a standard zoom, giving an angle of view equivalent to a 28-70mm lens on a full-frame camera.

Close focusing
Minimum focusing distance is just 28cm throughout the entire zoom range.

Superior optical performance
The EF17-40mm f/4L USM has 12 lens elements arranged in nine groups. Super Spectra coating ensures excellent colour balance and minimises ghosting and flare. To provide superb image quality over the complete 17-40mm zoom range the lens uses three aspheric elements. Super UD (Ultra-low Dispersion) glass prevents chromatic aberrations.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Non-rotating front element
The front of the lens does not rotate, which makes using specialised filters, such as polarisers and graduates, easier. A drop-in gelatine-filter holder can be found at the back of the lens.

Smooth background blur
A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background.

Weather resistant
Highly resistant to moisture and dust, the EF17-40mm f/4L USM is ideally suited for use in
