Description Lens Canon EF 28-300 mm f/3.5-5.6 L IS USM (9322A006)

Canon EF 28-300 3.5-5.6 L IS USM releases
Canon a professional zoom lens of superbig increase in EF28-300mm f/3.5-5.6L IS USM. Big range of zooming - about 11 krat - covers all provisions: from wide-angle to a telephoto. New - a heat - and the water-proof lens of Canon will allow professional photographers, removing the EOS cameras, to reduce the frequency of replacement and number of lenses which they should carry with themselves.

Stabilization of the image is applied by
In a lens the well-known technology of stabilization of the image (IS) developed by the Canon company allowing to increase exposure approximately by three steps without noticeable gain of blurring of the image when shooting static objects or panoramas. Thanks to it the circle of situations in which it is possible to remove from hands, without need to carry with itself a support considerably extends. If movement of the camera in one direction continues during certain time, the image stabilization system in mode 2 automatically determines that it is purposeful panning, and stops correction in the corresponding direction, preventing parasitic vibrations. In order to avoid errors when shooting from a support the system automatically reveals lack of movement/vibration.

Fast autofocusing
focus ultrasonic motor (USM) of ring type Located in a lens will transform energy of ultrasonic fluctuations owing to rotation, necessary for high-speed, high-precision, superefficient and almost silent autofocusing. At the same time the bezynertsionnost of the motor provides a fast and exact response. The lens is equipped with the system of constantly included manual focusing allowing to pass instantly into the manual mode without risk of damage of the mechanism of autofocusing. The minimum distance of focusing in all the range of zooming makes only 0.7 m

is ideal for the digital photo
Form and a covering of elements of a lens were improved for the purpose of suppression of an aura and flares on the image. Therefore it is ideal for the digital cameras more sensitive to reflection of light from the image sensor, than film devices. When using this lens on digital cameras with the APS-C size sensor, for example, on the EOS 10D model, it is possible to get advantage of additional increase as the range of focal distances (equivalent for a 35-mm film) is 45-480 mm.

with
high resolution on all area of the image at any focal distance. As well as all other lenses EF, new model it is equipped with an electromagnetic diaphragm (EMD) working quickly, silently and very precisely. Thanks to a round opening the diaphragm (completely opened or covered on 1-2 steps) can create attractive blurring effect of a background. Three elements from glass with ultralow dispersion (UD) allow to eliminate the residual chromatic aberrations which are inevitably arising in long lenses of lower class, and aspherical elements promote correction of the other aberrations appearing when zooming. Result - the unsurpassed clearness and sharpness of the image for which professional lenses of series L are famous.

in strict accordance with features of the latest models of the EOS cameras that allows to use advantages of its high-speed work as much as possible.
