Ultra wide-angle 16-35mm zoom lens
This high performance, fixed aperture, ultra wide-angle zoom lens combines excellent optical performance with flexibility, making it ideal for landscapes, architectural shots, photo journalism, travel and general use - delivering clear, sharp, expansive images with very little distortion.

L-series quality
The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture.

Constant f/4 aperture
Ideal for use in a wide range of light conditions, the f/4 maximum aperture stays constant over the full focal-length range, so there is no variation in shutter speed or ISO when zooming.

Sharp images with 4-stop Image Stabilizer
The EF 16-35mm f/4L IS USM delivers steady shots in all situations, particularly when shooting handheld in low light or at the macro setting. The lens incorporates Canon’s 4-stop Image Stabilizer technology and automatically detects normal shooting or panning motion, switching to the IS mode optimal for either situation.

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. Full-time manual override lets you fine tune focus without leaving AF mode.

Smooth background blur
A 9-blade circular aperture diaphragm gives out of focus regions a softer, more uniform feel – so your foreground subjects stand out sharply against beautiful, smooth background blur.

Superb image quality
The EF 16-35mm f/4L IS USM incorporates 3 aspherical elements to ensure corner-to-corner sharpness and clarity throughout the focal range. 2 UD (Ultra Low Dispersion) elements virtually eliminate chromatic aberrations. Super Spectra Coating ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting - a common problem caused by light bouncing off a camera's sensor. Fluorine coatings prevent dust and water droplets sticking to front and rear lens elements to help ensure optimum image quality.

0.28m minimum focusing distance
With only a 0.28m focusing distance through the entire zoom range, you can get closer to your subjects and still enjoy a wide field of view.

Non-rotating front element 
Easily attach 77mm filters thanks to the non-rotating front element.
