Canon EF 24-70mm f/2.8L USM Zoom Lens

This new lens does what many pros thought couldn't be done -- replace the previous L-series 28-70 f/2.8 lens with something even better. The Canon EF 24-70mm f-2.8L USM is a superb new professional lens that offers and even wider zoom range than its predecessor. Extended coverage to an ultra-wide angle 24mm makes it ideal for digital as well as film shooters. And the optics are even better than before. The Canon EF 24-70mm f-2.8L USM now offers two types of Aspherical elements and an entirely new UD glass element for superb optical performance even wide-open.

The Canon EF 24-70mm f-2.8L USM focuses closer than before, and even faster with revised electronics and a new processor. And it's now sealed and gasketed against dust and moisture at the lens mount, the zoom and focus rings, and the switch plate. The ultimate professional standard zoom lens just got better.

Key Features of the Canon EF 24-70mm f/2.8L USM Zoom Lens

Professional Standard Zoom Lens, Now With Wider 24mm Coverage

Constant Aperture of f/2.8 Throughout The Zoom Range

Ultrasonic Motor

Powered by Canon's exclusive Ultrasonic (USM) motor for autofocusing, the EF 24-70mm f-2.8L USM is silent in operation and very quick to focus, even in low-light conditions. There is virtually no whining noise as the lens focuses to distract the subject or draw attention to the photographer. Most important for the photographer in the field, the motor draws minimal power so the camera batteries last longer.

Two Aspherical Lens Elements

Wide-angle lenses and fast normal focal-length lenses often suffer from an optical problem -- spherical aberration -- which causes an overall softening and optical "smearing" of the image. Canon has developed four different manufacturing technologies to produce Aspherical lens elements, which combat this problem. Aspherical optics, which have an extremely precise variable curvature of one or both sides of a lens element, also allow more compact lens designs and permit lighter lenses with fewer elements.

Ultra-Low Dispersion UD Glass

The new EF 24-70mm f/2.8L USM is a professional zoom lens with high contrast and high resolving power. It is constructed using the finest optics including a UD (Ultra-Low Dispersion) glass element designed to correct chromatic aberrations, resulting in extremely sharp images with excellent color rendition.

Circular Aperture

This Canon lens features a new circular apertures diapragm unit, which uses curved aperture blades to provide for a more rounded opening as the lens is stopped down. It's especially effective at rendering out-of-focus background highlights as natural rounded shapes. Offers a more pleasing out-of-focus image.

Weather Resistant Design

The Canon EF 24-70mm f-2.8L USM is sealed and gasketed against dust and moisture at the lens mount, the zoom and focus rings, and the switch plate.

EF Lens Mount

In designing the EF lens mount, Canon engineers gave photographers a lot more than simply a way to quickly attach an interchangeable lens to a camera body. With the elimination of mechanical connections and the incorporation of an electronic interface between the camera and lens, Canon cameras have greater flexibility with regard to incorporating future technologies and future system upgrades. This fact has already been proven with a vast increase in AF speed, increased functionality such as predictive autofocus systems found in EOS cameras, auto-aperture tilt-shift (TS-E) lenses, the use of ultrasonic motors and the development of the Image Stabilizer lens.

The fully electronic mount system has none of the shock, operational noise, abrasion, play, lubrication requirements, slow response, diminished precision caused by lever operation, or design restrictions related to linkage mechanisms used to transfer data. Furthermore, operation and reliability are significantly improved. And, a lens operation self-test system, using the lens' built-in microcomputer, can even warn of malfunctions through the camera's LCD readout to help ensure high reliability.

Full-Time Manual Focus

Ring-type Ultrasonic Motor allows manual focusing without switching out of the auto mode, making this lens ideal for many photographic applications including sports, photojournalism, portraits, and landscapes.
