Canon EF-S 18-55mm f/3.5-5.6 IS SLR Lens

Equipped with Canon's Optical Image Stabilizer (IS) technology the Canon EF-S 18-55mm standard zoom lens is ideal for just about any application. IS technology compensates for camera shake by providing the equivalent effect of a shutter speed up to four stops faster. This allows you to take sharp handheld shots even in low-light conditions--a must for sports and nature photography. The lens also offers an aspherical lens element that corrects for aberration thus producing a topnotch image throughout the zoom range and a circular aperture that exquisitely renders out-of-focus backgrounds. Despite its minimal size weight and cost the lens expands the picture-taking possibilities any time slow shutter speeds are needed.

  • Focal Length & Maximum Aperture - 18-55mm f/3.5-5.6

  • Lens Construction - 16 elements in 12 groups including UD-glass and aspherical lenses

  • Diagonal Angle of View - 74 20' - 7 50' (with APS-C image sensors)

  • Focus Adjustment - Gear-driven

  • Closest Focusing Distance - 1.48 ft./0.45m (maximum close-up magnification 0.24x)

Canon EF-S 17-55mm f/2.8 IS USM Lens for Canon DSLR Cameras

To meet user demands for a fast EF-S zoom lens Canon has specially designed a new lens with a large aperture of f/2.8 for select Canon Digital SLR cameras.* The large circular aperture produces a shallow depth-of-field creating background blur that draws attention to the photographic subject. The lens construction includes UD and aspherical elements which deliver impressive image quality throughout the entire zoom range. Image Stabilizer lens groups shift to compensate for camera movement so that the image appears steady on the image plane ensuring clear crisp images even in dim light. With a Ring-type USM inner focusing and new AF algorithms this lens achieves autofocus quickly and quietly and with full-time mechanical manual focusing manually adjusting the focus is possible even in AF mode.

  • 17-55mm wide-angle zoom lens with f/2.8 maximum aperture for Canon DSLR cameras

  • AD and aspherical elements deliver impressive image quality through entire zoom range

  • Image Stabilizer lens groups shift to compensate for image shake even in dim lighting

  • Large circular aperture produces shallow depth of field; ring-type ultra-sonic monitor (USM)

  • Measures 3.3 inches in diameter and 4.4 inches long; weighs 22.8 ounces; 1-year warranty

Canon EF-S 60mm f/2.8 Macro USM Digital SLR Lens for EOS Digital SLR Cameras

A thoroughly modern design that's optimized for select Canon EOS digital SLRs. Its angle of view is equivalent to a 96mm lens on a 35mm camera with a floating optical system that can focus down to full life-size (1:1) magnification. Inner focusing driven by a silent and powerful ring-type USM means the lens' overall length never changes during focus. This lens is a wonderful multi-purpose lens that's equally at home shooting macro shots portraits or available-light photos. Like all Canon EF-S Lenses its use is restricted to the EOS 20D EOS Digital Rebel and EOS Digital Rebel XT cameras (as of February 2005).
