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.
The AF 75-300 f/4-5.6 extended-range zoom lens offers true telephoto capability ideal for a variety of applications including sports and wildlife shooting. The lens also features the capability to provide beautifully blurred background to high light the main subject in portraiture, or "compression effects" that make the most of the telephoto lens.
The AF-S VR 70-300 f/4.5-5.6G IF-ED is a high-performance super telephoto zoom lens that has been designed to meet the demands of both digital and 35mm format SLR users. It offers a 4.3x zoom with a range of 70-300mm (105-450mm on a DX Nikon D-SLR) and features ED (Extra-low Dispersion) glass elements that ensure superior optical performance. This lens incorporates Nikon's second-generation vibration reduction system (VR II) that allows flexible hand-held shooting by stabilizing the image to the equivalent extent of using a shutter speed that is four stops faster when compared with a conventional lens (as determined by Nikon performance test). The SWM (Silent Wave Motor) and IF (Internal Focusing) ensure fast and quiet focusing action, and the nine-blade rounded diaphragm makes out-of-focus elements blend smoothly to produce natural-looking, harmonious backgrounds.

Tamron now offers a lightweight, compact, high-image-quality telephoto zoom lens with macro capability of 1: 2 that can be used with digital cameras. This new lens is a Di type lens using an optical system with improved multi-coating designed to function with digital SLR cameras as well as film cameras.With this 70-300mm telephoto zoom lens, flipping a macro switch in the focal length range of 180mm to 300mm obtains a maximum magnification ratio of 1: 2 at a minimum focus distance as short as 37.4", enabling close-up shots of flowers, insects, and other objects that normally require the use of a specially designed macro lens. Moreover, this is a zoom lens that casually offers the distant capture and foreshortening effect pleasures of the 300mm ultra-telephoto world.
Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of the Di products. These lenses are not designed for 35mm film cameras and digital cameras with image sensors larger than 24mm x 16mm.At Tamron, quest has always been to make the ideal zoom lens. As a result of this ongoing challenge, Tamron has introduced the concept of the high-power zoom lens in the new AF18-200mm XR Di II for exclusive use with digital SLRs. Tamron's original development of proprietary core technologies such as Aspherical element production, Multiple Cam Mechanism and Integrated Focus Cam design lend to the creation of the world's lightest, most compact 11.1X zoom lens made for digital SLR cameras.The 18-200mm (28-300 when converted to 35mm) provides the digital photographer with the versatility of a true wide to ultra tele-zoom in an amazingly easy to use design.
With the advent of the latest 15X zoom lens from Tamron, the pioneer of high power zoom lenses, the high power zoom lens has steadily evolved from a 7.1X to a 10.7X to a 13.9X and now to the worlds largest zoom ratio of 15X by combining advanced high power zoom design technologies accumulated by Tamron since 1992. The lens covers an angle of view equivalent to that of a 28mm wideangle to a 419mm ultra telephoto with just one lens, letting the user capture once-in-the-lifetime images of panoramic landscape images or close-up pictures of children smiling, without having to get too close to the subject and without having to change lenses.
