CANON ZOOM LENSES

EF-S 10-22mm f/3.5-4.5 USM Zoom Lens

This exciting new zoom lens provides ultra wide-angle coverage to the EOS 20D camera and Digital Rebel camera shooter. Equivalent to a 16–35mm zoom for a 35mm film camera, it offers excellent performance and optics designed from the ground-up for digital SLR use. Excluding fisheye lenses, the EF-S 10-22mm f/3.5-4.5 USM lens has the shortest minimum focal length ever offered for interchangeable lens digital SLRs with APS-C image sensors.

Photographers will achieve consistently excellent image quality throughout the zoom range of this lens because of its 3 Aspherical elements and 1 Super-UD element in a 13-element optical formula. A ring-type ultrasonic focusing motor (USM) provides fast and silent AF along with full-time manual focus. Minimum focusing distance is 24 cm for breathtaking close-ups. The EF-S 10-22mm f/3.5-4.5 USM lens is relatively light and compact at 8.9 cm in length and a weight of 0.4 kg. The new lens accepts 77mm filters and can be fitted with an optional bayonet-mount lens hood.

EF-S 17-85MM f4-5.6 IS USM

This new EF-S lens brings true wide-angle to telephoto coverage to EOS 20D camera and Digital Rebel camera photographers. It features Canon’s Image Stabilization system, allowing safe hand-held photography at shutter speeds up to three steps slower than otherwise possible. And of course, it’s optically optimized for digital SLRs. A ring-type USM delivers fast and silent auto focus, as well as full-time manual focus when in the AF mode.

The EF-S 17-85mm f/4-5.6 IS USM lens provides a 5x zoom ratio and an angle of view equivalent to a 27-136mm lens on a 35mm camera. The new lens also uses a glass-molded aspherical lens element with aspherical surfaces on both sides for superb image quality throughout the entire zoom range and it features a closest focusing distance of 30 cm at all focal lengths. The EF-S 17-85mm IS lens is 5% shorter and 12% lighter than the EF 28-135mm IS lens and accepts 67mm filters.

EF-S 18-55mm f/3.5-5.6 USM Zoom Lens

This is the USM version of the popular EF-S 18-55mm f/3.5-5.6 zoom lens that is available in kit form with the EOS 20D camera and Digital Rebel camera. Both lenses have an angle of view equivalent to a 29-88mm lens on a 35mm camera. Weighing in at just 6 oz. and measuring 6.35 cm in length, the EF-S 18-55mm f/3.5-5.6 USM produces exceptional image quality in an ultra-compact package. The new lens accepts 58mm filters and features Canon’s exclusive Micro USM II focusing motor technology for swift and silent AF.

EF 16-35mmf/2.8L USM

- Three types of aspherical elements
- Highly resistant to dust and water droplets
- Inner focusing and ring USM for silent and high-speed AF operation
- Drop-in, gelatin filter holder provided at the rear
- Circular diaphragm for better background blur.
Developed to succeed the high-performance 17-35mm f/2.8L USM, the EF 16-35mmf/2.8L USM has the leading wide-angle range in its class. Due to the proliferation of digital SLR Camera's that tend to have a smaller frame size when compared to the 35mm,there is a demand for shorter focal length lenses, and this has resulted in the development of the EF 16-35mmf/2.8L USM. This is the first EF lens to have three types of aspherical elements (ground, replicated and glass molded which effectively correct the lens aberrations which occur during zooming.

EF 17-40mm f/4L USM

- Superb optical performance throughout the zoom range.
- Fastest AF speed within its class (same as the EF16-35 f/2.8L USM)*
- Highly dust and moisture resistant
- 28cm minimum focusing distance at all focal lengths
The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users. The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent color balance and minimizes ghosting and flare. To provide superb image quality over a 17-40mm zoom range the lens uses three aspheric elements of two different types, while Super UD (Ultra-low Dispersion) glass is used to prevent the chromatic aberrations that often can degrade the subject edge clarity. The Auto-focus works silently and quickly thanks to a fast central processing unit with an improved AF algorithm. You can override AF mode with manual focus should you wish. Controlled by an electromagnetic diaphragm, the EF17-40mm f/4L USM's circular aperture can achieve a more attractive appearance to out of focus background areas in a picture. The front of the lens does not rotate as you focus. This means, for example, that polarizing filters still function effectively as you zoom in and out. At the rear of the lens there's a drop-in gelatin filter holder. Highly resistant to moisture and dust, the EF17-40mm f/4L USM is ideally suited for use in harsh environments.

EF 20-35mm f/3.5-4.5 USM

- Focal length and maximum aperture: 20-35 mm 1:3.5-4.5

- Diagonal angle of view: 94°-63°
- Focus adjustment: Inner focusing system with USM
- Closest focusing distance: 0.34m / 1.1ft
- Filter size: 77mm
Highly portable lens with high optical performance and light weight of 340g. A very practical ultra-wide-angle zoom. The large front lens group minimizes peripheral darkening, and the flare-blocking diaphragm minimizes flare. Also, with lens group 2 being the zoom group, distortion is corrected.

EF 24-70mm f/2.8L USM

- High-speed AF
- Optimized lens coatings
- Highly resistant to dust and water droplets
- Min. focusing distance of 0.38m at all focal lengths
- Front of lens does not rotate during focusing
- Manual focus is possible in AF mode
- Only lead-free glass is used
The EF 28-70mm f/2.8L USM has proven very popular with professional and advanced amateur photographers since it was introduced in 1995. However, the increasing use of digital cameras, most having sensors smaller than a 35mm film frame, has increased the demand for a high-performance standard zoom lens with a wider wide-angle setting. The EF 24-70mm f/2.8L USM lens meets this need. The optical design is based on the previous lens, but incorporates new design features that allow the broader focal length range while maintaining the superb image quality. At the same time, the minimum focusing distance has been reduced from 0.5 meters to 0.38 meters. Improved water and dust resistance ensure that it will become the leading standard zoom lens in the EOS system.

EF 28-90mm f/4-5.6 II USM

- Compact, lightweight standard zoom lens
- Fastest AF speed in its class* when used with the EOS 300V
- Aspherical element used to maintain high image quality throughout the zoom range
- Optics use only lead-free glass
The EF 28-90mm f/4-5.6 II USM is designed as a standard zoom lens for the EOS 300V. It provides the fastest AF speed in its class when used with this camera. Faster all round performance is also delivered when the lens is used with other EOS models. To achieve this increased speed the EF 28-90mm f/4-5.6 II USM uses an AF drive pattern optimized for the EOS 300V, has a new type of CPU with increased communication speed, and features a new AF algorithm. The exterior design of the lens matches that of the EOS 300V and other EOS models. High image quality is ensured throughout the focal length range by the use of an aspherical element in one of the lens groups. This lens features the USM (Ultrasonic Motor) motor which operates almost noiseless. Only environmentally-friendly lead-free glass is used for the optics.

EF 28-90mm f/4-5.6 II

- Compact, lightweight standard zoom lens
- Among the lenses with the fastest AF speed in its class
- Aspherical element used to maintain high image quality throughout the zoom range
- Optics use only lead-free glass

EF 28-105mm f/4-5.6 USM

- Among the lenses with fastest AF speed in it's class
- Light weight and small size
- Circular aperture at max settings
- Micro USM II
- Inner focusing means attached filters do not rotate
- Environmental friendly lead-free glass used* as of Aug 27, 2002
The EF 28-105mm f/4-5.6 USM uses an aspherical lens element to maintain a high image quality throughout the zoom range. All the lens elements are made from environmentally friendly lead-free glass. The small size of the lens is due, in part, to the use of a new type of AF drive actuator. The Micro USM II is a minute ultrasonic motor that retains a similar level of performance as previous Micro USMs, but has a total length - as well as weight - reduced by almost one half. The AF speed is the fastest in its class when used with the EOS 300V but also faster all round performance is delivered when the lens is used with other EOS models. With inner focusing, the front lens does not rotate during focusing. Various accessories can therefore be attached to the front lens without being hindered by lens rotation or movement.
