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 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras

This new lens does what many pros thought couldn't be done - replace the previous L-series 28-70 f/2.8 lens with something even better. Extended coverage to an ultra-wide-angle 24mm makes it ideal for digital as well as film shooters and the optics are even better than before with two Aspherical elements and a totally new UD glass element. It's now sealed and gasketed against dust and moisture and a new processing unit makes the AF faster than ever.
