Canon EF 17-40mm f/4L USM Wide Angle Zoom Lens

17-40mm f/4L USM Wide Angle Zoom Lens from Canon

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. A Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast in difficult lighting conditions. Complementing the imaging capabilities, this wide-angle zoom also features a ring-type USM and internal focusing mechanism to afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override.

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 harsh environments. Environment friendly lead-free glass is used throughout its construction.

Canon European Warranty System Information

In the event that a Canon product develops a fault, our customers are covered by the Canon European Warranty System (EWS) which ensures that the fault is resolved free of charge for a limited period of time after purchase (terms and conditions apply).

Terms and Conditions
The EWS is comprised of two different service offerings and the offering that is applicable to you is determined by your location and the product you have purchased. For most Canon consumer products, a Return To Base service is offered. If a product develops a manufacturing fault during the warranty period then it must be returned to a Canon approved repair facility where it will be repaired free of charge by Canon authorised technicians. Your product will be returned to you when the repair is complete.

A: Technically, Canon warranties are only applicable within the region in which the product has been sold and for which specific warranty details were included in the box. Canon does not generally offer a global warranty unless specifically mentioned for specific products / regions. We would always advise Canon customers to contact local Canon representatives to see what assistance is possible.

To support your claim we would always advise you to retain any applicable documentation relating to charges incurred / repairs handled.
