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 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs

With its effective focal length range of approximately 16-35mm in 35mm format the EF-S 10-22mm f/3. 5-4. 5 USM is a remarkable lens with outstanding image quality that will take your photography into new dimensions and areas of dramatic expression. The super-wide zoom not only gives you the freedom to get exactly what you want in the shot it dramatically alters perspective to allow for dynamic expression. The lens allows you to get extremely close to subjects exaggerating the difference in size between a near object and its background. Creative photographers can use this phenomenon to create excellent separation between subject and background for a strong sense of presence or for a pan-focus effect with everything from foreground to background sharply in focus. Exceptionally light and compact for its focal length range the EF-S 10-22mm f/3. 5-4. 5 USM also has an incredibly close minimum focusing distance of just 24cm. A ring-type USM works in concert with the camera to provide super-fast precision auto focusing and predictive tracking - with full manual override available at any time. Designed specifically for digital photography the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare. A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and getting your subject or model to stand out from the background.

  • 10-22mm wide-angle zoom lens with f/3.5-4.5 maximum aperture for EOS digital SLR cameras

  • Superior AF performance and speed with full-time manual focus with the turn of a ring

  • Close focusing to 9.5 inches; fills the frame with subjects as small as 3.6 x 5.4 inches

  • Circular aperture design produces natural highlights
