Product Description

Canon's first zoom lens with DO elements

A new triple-layered diffractive optical element (DO) has enabled Canon to produce a 70-300mm lens less than 10cm long. The EF 70-300mm f4.5-5.6 DO IS USM also includes Canons Image Stabilisation technology to dramatically reduce camera shake, compensating for approximately three stops in shutter speed without any perceptible increase in image blur. A virtually silent ultra-sonic motor (USM) gives the lens extremely fast autofocus.

"This lens is symbolic of Canon's leadership in precision optics", said Mr. Komatsuzaki, Head of Canon Consumer Imaging Europe, at the lens launch. 'Canon stands alone as the only company to have successfully commercialised Diffractive Optical elements in camera lenses, and the results speak for themselves."
Full time manual focusing, a circular aperture diaphragm, and a zoom ring lock mechanism to fix the lens at the shortest focal length are all built in. The lens boasts image quality approximating that of Canon's L series professional lenses. It is likely to appeal to professional photojournalists and serious advanced amateurs with a need to contain the size and weight of equipment carried.

DO Elements
This is the first DO lens to be released by Canon since the EF 400mm f/4 DO IS USM. Use of the new three-layer DO lens drastically reduces the overall length and weight of the lens system increasing the refractive power of each lens element and reducing the spaces between elements. Chromatic aberration normally associated with increased compactness is corrected by positioning the three-layer type DO lens on the front lens side. This, coupled with the correction of spherical aberration through the use of aspherical surfaces, delivers high image quality and high levels of resolution and contrast, rivalling the performance of Canons legendary L-series lenses.

Zoom lock
The EF 70-300mm f4.5-5.6 DO IS USM features a zoom ring locking mechanism, locking the lens at its shortest total length. This helps to protect the lens from potential damage by preventing the zoom elements extending under their own weight. This might otherwise occur when the lens is mounted to a camera that hangs from a neck or shoulder strap.

Image Stabilisation
The lens incorporates Canons Image Stabilisation (IS) technology, compensating for approximately three stops without any perceptible increase in image blur when shooting static subjects or panning.
This vastly increases the range of circumstances in which hand-held photography is possible, limiting the need to carry a tripod. During major movement in a single direction, IS Mode 2 technology automatically determines that the movement is intentional panning and halts correction in the relevant direction, thereby preventing shake-return. The IS system automatically detects lack of movement/vibration to prevent operation errors when a tripod is used. The increase in IS efficiency and the lower overall size have been achieved through improvements in the moving contact sections of the IS lens barrel, the IS lens group barrel locking mechanism and the shake-detection gyro.

Fast AF
A rear focusing ring type USM, high-speed CPU and new AF algorithms combine to give the lens extremely fast auto-focusing. The ring-type ultrasonic motor (USM) converts ultrasonic vibrational energy into rotational force to deliver high-speed, high-precision, super efficient and virtually noiseless auto focusing, with good holding torque for rapid response and accurate stopping. Full-time manual override is featured, removing the possibility of damage to the autofocus mechanism during manual focus. The lens has a minimum focusing distance of just 1.4m throughout the entire zoom range.

Ideal for digital
The lens element design has been optimised and new coatings added to suppress ghosting and flaring. This makes the lens ideal for use with digital cameras that are more susceptible to reflections off the recording media than film cameras.

Attractive defocusing
Refractive and DO elements are combined to realise low distortion, high corner-to-corner resolution throughout the entire zoom range. As with all EF lenses, aperture is controlled with an EMD (electromagnetic diaphragm) for fast, quiet, highly precise control and the lens incorporates a near circular aperture diaphragm for beautifully pleasing background blur.

Working with EOS
The drive pattern of the lens is tailored to specifically match that of the latest models in the EOS camera range, extracting maximum benefit from the speed advantage of the lens. The lens comes with a case LP1116 and an exclusive hood ET-65B for shading against unwanted direct light.

Lead free
In keeping with Canon's stringent environmental policy, only lead free glass is used in the lens' optics.
