The Canon 4409B002 Extender EF 1.4x III Lens extends a lenses focal length by a factor of 1.4x. Extender EF 1.4X III incorporates phenomenal optical performance with minimal chromatic aberration and is a perfect complement to many of Canon super telephoto lenses. It features a built-in microcomputer for seamless communication among camera body, lens and extender; features careful lens placement and coatings to minimize ghosting and flare and even has a new Fluorine coating that keeps soiling, smears and fingerprints to a minimum. An integral part of many professional systems, Extender EF 1.4X III maintains high standards not only optically, but also in terms of rugged, dustproof and water resistant constructionEF Mount Teleconverter|1.4x Magnification Factor|Microcomputer Controlled|Communication Between Lens & Camera|Spectra Coating Reduces Ghosting/ Flare|Protective Fluorine Coating|Dust and Water Resistant|Compatible with Select EF Mount Lenses|7 elements in 3 groups lens construction| canon| 4409b002| extender ef 1.4x iii lens| extender| ef| 1.4x| iii| lens Package Contents: extender ef|extender cap|lens dust cap (rear)|lens case|manual|warranty This item cannot be shipped to APO/FPO addresses

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.

This ultra-wide-angle lens has the shortest focal length in the L-series. Element 2 is an aspherical lens to correct distortion. Other aberrations such as astigmatism are also corrected, resulting in ideal image quality. The lens has a fixed, petal-type hood and a gelatin filter holder at the rear.

Standard lens featuring superb quality and portability. Two high-refraction lens elements and new Gaussian optics eliminate astigmatism and suppress astigmatic difference. Crisp images with little flare are obtained even at the maximum aperture.

One of the finest telephoto zoom lenses in the EF line, comparable to a single focal length lens. It has four UD-glass elements to correct chromatic aberrations. Its constant f/2.8 maximum aperture and superb image quality make it one of the most popular professional SLR lenses in the world. Compatible with Extender EF 1.4x II and 2x II.

Canon LA-DC52B Lens Adapter for PowerShot A30 & A40 Digital Cameras.The lens adapter Provides a 52mm filter mount for adding Wide Angle & Telephoto Lenses and filters or other lens accessories to the Canon PowerShot A30 and A40 Digital Cameras.

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.

• Light and compact IS-equipped telephoto zoom lens specifically for cameras that take EF-S lenses.
• Automatically distinguishes between normal shooting and panning shots and selects the optimum Image Stabilizer mode.
• Image Stabilizer effect equivalent to a shutter speed around 4 settings faster.
