A perspective equivalent to 24 mm on a 35 mm film camera lenses enhances the versatility of this standard lens.
High-performance standard zoom lens will achieve the world's fastest-class AF speed thanks to SWD. Fully compensates for distortion and uses ED lens components extensively to assure high imaging performance with high contrast till the image peripheries.

Uses three ED lens components to minimize color aberrations. The fast AF system frees the user to focus on more creative photography.
Ultra-telescope zoom lens covering a wide zoom range equivalent to 100-400 mm on a 35 mm film camera lens and featuring ultra-fast AF drive. Three ED lens components are used to ensure compatibility between the brightness of the large f2.8-3.5 aperture and high image quality. An inner focus mechanism is used to achieve a minimum shooting distance of 1.2 meters throughout the zooming range.

Boasting the industry's highest imaging performance, this is the world's first large-aperture standard zoom lens to achieve f2.0 throughout the zooming range. Uses ED and aspherical ED lens components to correct aberrations, while the SWD ultrahigh-speed autofocusing and mechanically linked manual focusing mechanism enable stress-free focusing operations.
