Canon EF 24-70mm f2.8L II USM

Meeting the ever-increasing demands on image quality that digital photography brings, the redesigned EF 24-70mm f/2.8L II USM re-establishes a new standard for superb optics, high-end durable construction, and performance in professional zoom lenses. A standard focal length zoom lens, it features a large aperture throughout its focal length. This lens is perfect journalists, wedding, and portrait photographers.

The Technical Details

Featuring the latest advances in optical lens design, it utilizes 1 Super UD lens element and 2 UD lens elements that help minimize chromatic aberration in the periphery at wide-angle as well as reduced colour blurring around the edges of the subject. In addition, 2 types of aspherical lenses are combined to help reduce spherical aberration over the entire image area as well as through the full zoom range. Optimized lens coatings also help ensure exceptional colour balance while minimizing ghosting. The lens is also equipped with a circular 9-blade diaphragm for beautiful, soft backgrounds. A ring-type USM and high-speed CPU with optimized AF algorithms enable silent and fast autofocusing. Built for the rigors of professional use as well as to meet the increased number of shots available with digital photography, it's constructed with improved dust sealing and water resistance while fluorine coatings on the front and rear lens surfaces help reduce soiling, smears, and fingerprints. A zoom lock lever locks the zoom position at the wide end for safe transporting while attached to an EOS DSLR camera over the shoulder.

Ring-type USM (Ultra Sonic Motor)

Ring-type motors are highly efficient and feature a low power consumption to extend the camera battery life. Being ring-shaped, they are ideally suited to the shape of the lens barrel, their focusing speed is very controlled and they are stable across a wide range of temperatures, from -30°c to 60°c. They enable quick and silent auto focus of Canon Lenses.

L-Series Lenses

L-series lenses meet the requirements, and needs of professionals. Canon uses three technologies in its L-series lenses to produce the sharpest, clearest pictures: fluorite elements, aspherical elements and UD optical glass elements. To make sure you can easily identify these luxury lenses, Canon marks them with a red ring around the lens barrel. If it does not have this red ring, it is not part of the L-series lens range.

Built to Last

Optical performance is only half the story. A lens destined for professional use must be able to withstand the rigours of a professional photographer’s working life. This means a rugged build quality that will endure the knocks of everyday use, and weather sealing to protect against every type of adverse conditions. Accordingly, the L-series lenses feature liberal use of rubber sealing at interface areas, such as the lens-to-camera junction, external switches, and around zoom and focus rings to prevent water getting in and destroying the lens’ electronics.

Low Light Limits

Professional photographers are often forced to shoot in less than ideal lighting conditions. Sometimes this can mean in low light or even at night. The L-series offers wider maximum apertures than other lenses.
