Versatile ultra-wide zoom

On full-frame cameras, the ultra-wide 17mm angle is perfect for capturing sweeping landscapes, architecture and street photography, as well as situations like large group photos at weddings. The full 17-40mm zoom range however offers great variety – and with a minimum focusing distance of just 28cm, you can truly get up close to your subject and capture the detail, whether it’s a person, an object or the food on your plate! Like other Canon L-series lenses, this EF lens is also compatible with Canon APS-C sensor cameras, to offer an equivalent of a 28-70mm zoom.

Impeccable colours

The Canon EF 17-40mm f/4L USM Lens is a fabulous lens for shooters who enjoy shooting the beauty of landscapes, travel and street photography, and can come in handy in a range of everyday shooting conditions. This lens features many quality, thoughtful features, and has been designed with 12 lens elements in 9 groups – including Super Ultra Low Dispersion glass and three aspherical lenses for precise correction of chromatic aberrations. A Super Spectra Coating on the elements assists to reduce flare and ghosting and deliver lovely colour reproduction.

Wide aperture range

Even if you zoom in on details like flower petals or fruit bulbs in the field, the f/4 maximum aperture remains constant, so you can maintain control over depth of field and let plenty of light into your shot. That also means you don’t have to change your ISO or shutter speed constantly when zooming in and out with the lens to get the right settings. Constructed with 7 aperture blades, this ultra-wide angle lens can create beautifully smooth bokeh for out of focus background effects in images, which is ideal for portraits.

Superb autofocus and durability

This beautiful lens flaunts an ultrasonic autofocus motor, which delivers fast and precise autofocusing that is also wonderfully silent. Wherever and whatever you’re shooting, you can trust this lens will keep up, do a great job and not make a sound – perfect for shooting in nature. The whole setup is encased in a dust-resistant and moisture-resistant body, ensuring maximum durability.

Versatile and portable

At just 475 grams – less than half a kilo – this Canon lens is comfortable to carry around with you, and is especially handy for travel. This lens has easily become a favourite of photographers around the world, as it is not too heavy to lug around nor too light that you might miss it. Its versatility in weight and size is just perfect. When on camera, it makes it easy for you to stash in a medium carry-on bag.
