Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR Cameras

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)

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)
