Features:
A highly practical medium telephoto lens with superb delineation and portability. Images are sharp and clear at all apertures. Through computer simulations, the lens has been designed to give beautiful background blur. Since the front lens group does not rotate during focusing, special filter effects are not affected.

Features:
This large
aperture, super high image quality telephoto zoom lens provides performance
comparable to that of a single focal length lens, with a wide zoom range. Its major features include: a ring USM (Ultrasonic Motor) drive, built-in full-time manual focusing, short minimum focusing distance of 1.5m, high marginal illumination, and compatibility with Extenders EF1.4X and EF2X (extends the zoom range with AF to 98-280mm f/4 or 140-400mm f/5.6 respectively). Although this is a large aperture telephoto zoom lens, it is equipped with four low refraction/low dispersion UD (Ultra-low Dispersion) glass lens elements (2nd,3rd,11th & 13th) that offer excellent contrast and sharpness. This is a lens that deserves to be known as a super high performance telephoto zoom lens.

Features:
A compact and lightweight 300mm super-telephoto lens with Image
Stabilizer(IS). The Image Stabilizer shifts a lens group(11th to 13th elements) in parallel to the film plane. Camera shake is a major cause of blurred images especially with telephoto lenses. The IS system helps resolving this problem. The image stabilizing effect is equivalent to about two steps of shutter speed. "IS Mode 2" is newly applied to stabilize finder images at panning shots of moving subjects. The optical system uses two UD (Ultra-low Dispersion) glass lens elements(2nd & 5th) to compensate secondary spectrum and provide sharp, high-contrast images from maximum aperture.
