Canon EF 70-200mm f/4L USM Telephoto Zoom Lens for Canon 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)

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.

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.

MODEL- 2519A003 VENDOR- CANON

FEATURES- EF 85mm f/1.8 USM Lens
Sharp. Lightweight. Responsive. These are just a few adjectives that
describe this terrific portrait-length telephoto lens. With a
powerful ring-type USM and fast f/1.8 aperture subjects zip into
focus in the viewfinder. It is great for all types of work calling
for moderate telephoto power but comes into its own low-light
situations and offers a 1/3-stop speed advantage over the 100mm
f/2 USB lens.
* Ultrasonic Motor
In order to achieve critical autofocus the elements within a camera
lens have to move quickly quietly and precisely. With this in mind
Canon developed the worlds first lens-based Ultrasonic Motor (USM)
which spins the lens motor with ultrasonic oscillation energy.
Instead of a large noisy drive-train system electronic vibrations
create by piezoelectric ceramic elements power the mechanical action of
the lens providing constant torque with virtually instantaneous stops
and starts. USM lenses are both faster and quieter than conventional
motor driven autofocus systems and draw minimal power from the camera
draining very little battery power.

Canon EF-S 55-250mm f/4-5.6 IS Telephoto Zoom Lens

L2) CANON 70-300MM F/4-5.6 IS USM LE

This is considered the standard lens for use with Canon SLR cameras

Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens.

This telephoto zoom lens is designed with Canon’s Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon’s 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. This new EF-S telephoto lens with great features delivers excellent performance at an affordable price for all photographers.
