EF-S 60mm f2.8 Macro USM
The ‘S’ after ‘EF’ tells you this is one of a small group of lenses – and the first with a fixed focal length – exclusive to a small group of EOS cameras.
The EF-S lens mount was introduced a mere 18 months ago with the EOS 300D camera. It is designed for recent digital cameras with a sensor smaller than the standard 35mm frame. The lens does not need to cover such a large area inside the camera, so can be made smaller. In addition to the EOS 300D, the EF-S mount is found the the EOS 20D, and now the EOS 350D. These three cameras can still use all the lenses in the extensive EF range, but other cameras cannot use EF-S lenses.
Why a 60mm Macro? Well, the 100mm Macro is one of the best-selling fixed focal length lenses in the EF range. But fitting a 100mm lens to a camera with a sensor smaller than a 35mm frame gives a narrower field-of-view than you would getting using the lens on a 35mm camera. By choosing 60mm as the focal length for the new macro lens, it gives a similar field-of-view on an EOS 350D, 300D or 20D to the 100mm Macro lens on a 35mm camera.
The lens uses inner focusing (the filter mount does not rotate during focusing), and has new algorithms for fast autofocusing.

Canon launches the EF-S 60mm f/2.8 Macro USM lens
New for Canon D-SLRs
Canon, leader in photographic and imaging technology, is pleased to announce the launch of the EF-S 60mm f/2.8 Macro USM lens. Targeted at advanced and creative D-SLR photographers, the lens exclusively fits those digital EOS cameras with an APS-C size sensor and an EF-S lens mount - the EOS 20D, EOS 300D and the new EOS 350D. Featuring a true 1:1 macro magnification ratio, the lens has a focal length equivalent of 96mm in the 35mm format. This very closely matches the EF 100mm f/2.8 Macro USM, Canon’s most popular single focal length lens.
The lens features Canon’s ring-type Ultra Sonic Motor (USM) for fast, near-silent auto focus, a new AF algorithm for improved focusing speed, a close focusing distance of just 0.2m and a range of optical features designed to deliver high levels of image quality.
The APS-C sized sensor on the compatible EOS D-SLR cameras gives them an effective multiplication factor of 1.6x the indicated focal length – creating an obvious advantage for macro photography. The ‘S’ in the EF-S nomenclature stands for the term ‘short back focus’. This describes the system that allows for a smaller image circle and positioning of the rear lens element closer than normal to the camera’s image sensor. A white lens mount index differentiates the lens from other EF lenses, which retain their traditional red marking. A rear rubber ring prevents any damage in the event that an accidental attempt is made to mount the lens on incompatible cameras.
The lens has a 12 element, 8 group construction, and a three group inner focus system that delivers crisp, high contrast corner-to-corner detail. An internal 3 group focusing system allows the lens length to remain fixed when the focus ring is turned. This makes it ideal for set ups where the lens is very close to foreground subject matter, and for use with Canon’s lens mounted macro flash systems; the MT-24EX and MR-14EX twin and ring flash units.
The lens’ ring-type USM motor employs ultra-sonic frequency vibrations to drive focusing with unrivalled speed. Canon’s ring-type USM holds the lens with precision and accuracy, the instant it arrives at the correct focus and without overshoot. The lens drive algorithm has been enhanced to further improve focus accuracy and speed. The lens also features full-time manual focus override without risk of motor damage.
Appealing background blur
An EMD (electromagnetic diaphragm) barrel aperture helps to create attractive, even background blur when the photographer minimises depth of field to isolate a subject. This combines with the 60mm focal length to suit the lens perfectly to portrait photography.
Perfect for digital photography
By optimising Super Spectra lens coatings, Canon’s engineers have been effective in suppressing flare and ghosting, which are more prone to occur with digital cameras due to the relatively reflective nature of image sensors. By absorbing light, coatings reduce reflections off lens surfaces to deliver crisp, undistorted digital images with natural colour balance.
Distance linked flash
The lens passes distance information to the camera body, to provide compatibility with the E-TTL II flash system of the EOS 20D and EOS 350D. When used in conjunction with Canon’s range of EX Speedlite flash units, this allows for markedly improved flash exposure metering.
An optional lens hood accessory is available. The EF-S 60mm f/2.8 Macro USM can be used with the Canon extension tubes EF 12 II and EF 25 II for even closer focusing and larger than life images.
In harmony with the environment
In keeping with Canon’s stringent environmental policy, only lead free glass is used in the lens’ optics.
