Amazon.com Product Description
This compact and lightweight EF 75-300mm telephoto zoom lens is ideal for shooting sports, portraits, and wildlife. The lens is distinguished by a newly developed micro ultra-sonic monitor (USM) that makes autofocusing quicker and quieter, along with an improved zoom mechanism that includes a silver ring on the front for a luxurious touch. The micro USM makes this version of the lens particularly suitable for applications that require a fast autofocus, such as sporting events or wildlife shoots. Best of all, the USM version shares many of the same features that makes the non-USM lens so popular, such as a compact size, a close focusing range, and accessory compatibility. As with all Canon lenses, this unit carries a one-year warranty.

Amazon.com Product Description
Bring small things into full-sized view with the Canon EF 60mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The 60mm lens offers an angle of view that's equivalent to a 96mm lens on a 35mm camera, along with a floating optical system that can focus down to life-size 1:1 magnification. The inner focusing system, meanwhile, is driven by a silent and powerful ring-type ultra-sonic monitor (USM), meaning the lens's overall length never changes during focus. Ultimately, the multi-purpose lens is equally at home shooting macro shots, portraits, or available-light photos. Like all Canon EF-S lenses, this lens is restricted to the EOS 20D, EOS Digital Rebel, and EOS Digital Rebel XT cameras.

• Focal length: 60mm
• Maximum aperture: 1:2.8

Bring small things into full-sized view with the Canon EF 100mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The lens offers such features as a three-group floating system for exceptional close-up performance; a secondary diaphragm that blocks stray light at f/2.8, which increases contrast when shooting wide open; a ultra-sonic monitor (USM) that provides outstanding autofocusing speed at all focusing distances; a wide manual focusing ring with smooth action; and full-time manual focus even in AF mode. The first lens in its class to feature inner focusing, the lens carries a one-year warranty.

Product Description
The L-series is Canon's flagship professional lens range, designed to include outstanding image performance, ultimate operability and weather resistance. The EF 24-105mm f/4L IS USM offers a lightweight alternative to the renowned EF 24-70mm f/2.8L USM. offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 105mm without having to vary the shutter speed.

Image Stabilizer (IS) dramatically reduces image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. The 3 stop advantage means that photographers normally shooting a 105mm lens handheld at 1/125 sec can obtain a shake free result with a shutter speed as low as 1/15 sec, for vastly extended options in low light conditions.

The ring-type USM motor found in the EF 24-105mm f/4L IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improved AF algorithm contribute to speed performance. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. Photographers can choose manual focus instantly and at any time simply by moving the manual focus ring without first having to switch out of auto focus mode. Circular aperture producing attractive background defocus Inner focusing, ring USM and new AF algorithms for fast and quiet autofocusing Manual focusing enabled even during AF mode (full-time mechanical manual focus) Only environmentally friendly lead-free glass used in lens construction Filter diameter 77 mm / Dimensions (dia x len)

Product Description
AF is super-fast and silent with a ring-type USM, and it focuses down to 4.6 feet without rotating the front element. A new zoom lock button keeps the lens safe and secure when not in use or used at the wide angle.
Amazon.com Product Description
Canon raises the stakes for professional photography with its EF 70-300mm f/4.5-5.6 DO IS USM telephoto lens with image stabilization. Thanks to a new triple-layered diffractive optical element (DO), this 70-300mm lens is less than 4 inches (10 cm) long. It can focus down to 4.6 feet (without rotating the front element) and a new zoom lock button keeps the lens safe and secure when not in use or used at the wide angle. A virtually silent ultra-sonic motor (USM) gives the lens extremely fast autofocus. The lens also includes Canon's Image Stabilization technology to dramatically reduce camera shake, compensating for approximately three stops in shutter speed without any perceptible increase in image blur. It's a great choice for professional photojournalists and serious advanced amateurs who need to contain the size and weight of equipment carried.

DO Elements
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. It's approximately 26 percent shorter and 36 percent lighter than any lens of comparable specifications.

Zoom lock
The EF 70-300mm lens 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, which might otherwise occur when the lens is mounted to a camera that hangs from a neck or shoulder strap.

Image Stabilization
The lens incorporates Canon's Image Stabilization (IS) technology, compensating for approximately three stops without any perceptible increase in image blur when shooting static subjects or panning. This increases the range of circumstances in which hand-held photography is possible, limiting the need to carry a tripod.

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.

Ready for Digital Photography
The lens shape and coatings have been optimized to suppress ghosting and flaring, making this lens ideal for use with digital cameras that are more susceptible to reflections off the recording media than are film cameras.

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

Product Description
CANON 85mm f 1.8 Series EF USM Telephoto Lens -- A medium telephoto prime lens (not a zoom lens) with outstanding delineation and practical light weight.
Amazon.com Product Description
A highly practical medium telephoto lens with superb delineation and portability, the Canon EF 85mm lens produces sharp and clear images at all apertures. Through computer simulations, the lens has been designed to give beautiful background blur, thereby bringing your subject into crisp view. The ring-type ultra-sonic monitor (USM) and fast f/1.8 aperture, meanwhile, helps the subject zip into focus in the viewfinder. And because the front lens group does not rotate during focusing, special filter effects are not affected. Best of all, the standard zoom lens--with its natural angle of view and perspective--captures the subject plainly, making it excellent for portraits and images that require a natural depth of field. As with all Canon lenses, the lens carries a one-year warranty.

• Focal length: 85mm
• Maximum aperture: 1:1.8
• Lens construction: 9 elements in 7 groups
• Diagonal angle of view: 28 degrees (at 30 feet)
• Focus adjustment: Rear focusing system with USM
• Closest focusing distance: 2.8 feet
• Filter size: 58mm
