Product introduction

The camera shake correction is installed in ultra-high magnification zoom which realized wide-angle 28 mm.

In the optical system, three UD lenses and aspheric lenses are adopted, and the high image quality suitable for the L lens which thoroughly eliminated various aberrations as well as the camera shake correction effect for about 3 shutter speeds is realized.

Inner Focus, Ring USM Drive, AF in a quiet and agile way.

It is encouraging even under severe shooting conditions, and it also has high dust and drip resistance performance.

From Amazon

■ Aspheric lens

Spherical aberration correction of large aperture lens, distortion aberration correction of wide angle lens, miniaturization of zoom lens.

Aspherical lenses were born to solve these three themes.

■ UD lens

Ideal chromatic aberration correction with more lenses.

Under this theme, UD (Ultra Low Dispersion) lenses were developed.

It is highly effective in eliminating secondary spectra, has optical properties with low refraction and low dispersion characteristics, and anomalous dispersion characteristics like fluorite, and it has performance comparable to 1 fluorite in 2 sheets.

■ IMAGE STABILIZER

Canon's first image stabilizer IS (Image Stabilizer) for single lens reflex cameras installed in the world.

It is effective in the scene which is likely to cause camera shake, such as hand-held photography of a telephoto lens.

■ Ring USM

USM (Ultrasonic Motor) = Ultrasonic motor supports high focus / high response, quick focusing.

It has ideal characteristics as a lens driving motor, such as little operation noise.

■ Inner Focus

A technology to reduce the total weight of moving lenses by using a part of the lens configuration as a focusing lens.

It realizes high-speed and precise AF control, excellent holding balance, and compactness.

■ Full time manual focus

After autofocus, manual focus can be instantly done just by rotating the focus ring after one shot AF so that the photographer can finally adjust the focus.

■ Dustproof and drip-proof

We make various parts dust-proof / drip-resistant high structure corresponding to professional harsh photographing situation, and prevent intrusion of dust and water drops.
