The Canon 70-300mm f4.5-5.6 DO IS lens, a new agility and creativity in telephoto zoom lenses.

The world's first camera zoom lens with a DO element. A triumph of precision optics delivers compact size, low weight and ultimate image quality.

The EF 70-300mm f/4.5-5.6 DO IS USM is the world's only zoom lens to incorporate a DO element.

The introduction of a new triple-layered DO element not only makes the lens more nimble, it delivers unrivalled imaging performance. The DO element is combined with normal refraction elements to compensate for colour aberration. This achieves levels of colour aberration correction that could previously only be achieved with the use of fluorite elements or Ultra-low Dispersion (UD) lenses. The result: superb image quality in an exceptionally small package. Utilizing Ring USM (Ultrasonic Motor), the Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens focuses very fast in reasonable light. The Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens is an excellent travel lens.
