Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR CamerasCanon 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 100mm f/2.8 Macro USM Lens for Canon SLR CamerasCanon EF 100mm f/2.8 Macro USM Lens for Canon SLR Cameras


Autofocus lens for macro photography up to life-size (1x) magnification. Inner focusing affords a long working distance of 5.9in. (149mm) at 1x. A 3-group floating system results in excellent delineation at all focusing distances.

Ring USM for silent and high-speed AF, and full-time manual focusing also provided. The optional Tripod Mount Ring (B) B (with adapter) enables the lens to be rotated for vertical or horizontal framing.


Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRsCanon 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.

Canon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR CamerasCanon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR Cameras

Canon EF 70-200mm f/4L IS USM lens 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 200mm without having to decrease shutter speed. Developed for use with a Canon SLR camera, this autofocus telephoto zoom lens offers optimized use with the Canon EOS series digital cameras. Of particular note, Canon has introduced an image stabilizer (IS) that adjusts to meet the demands of professional photography. IS reduces dramatically the 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. For shooting immobile subjects, Mode 1 corrects for movement in the image along both the horizontal and vertical axes. For shooting while panning horizontally to follow a moving subject, Mode 2 turns off vertical correction and prevents the effect of dragging the subject back through the frame. The lens' Ring-type 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. The EF 70-200mm f/4L IS USM includes distance metering information, providing compatibility with the E-TTL II flash system of late model cameras such as the EOS-1D Mark II, EOS-1Ds Mark II, EOS 5D and EOS 400D. When used in conjunction with Canon's range of EX Speedlite flash units, the lens passes distance information to the flash algorithm for markedly improved flash exposure metering. Includes Lens hood and soft pouch
