Product introduction

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.

Ideal chromatic aberration correction with more lenses.

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

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.

Features

The shortest shooting distance 0.15 m.

It is the world's first * fisheye lens realizing real full fisheye effect (full circumference fish eye and diagonal fisheye in full size, diagonal fish eye in APS - C / H size) with three different imaging elements.

By adopting UD lens and high precision GMo aspheric lens, high resolution and high contrast high image quality suitable for L lens is realized.

It has high dustproof and drip-proof performance and durability.

* As an interchangeable lens for single lens reflex cameras.

■ 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.

■ 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.

■ SWC (Subwavelength Structure Coating)

Special coating SWC (Subwavelength Structure Coating) is a new antireflection technology that suppresses reflection of light by arranging innumerable nano-sized wedge-shaped structures smaller than the wavelength of visible light on the surface of the lens.

Even with lenses with large curvature such as wide-angle lenses, the occurrence of flare and ghosts in the periphery can be suppressed considerably.

■ Fluorine coating

New coating technology developed for the purpose of easy removal of dirt attached to the lens surface.

That is fluorine coating.

High in oil repellency and water repellency, it can be removed with a dry cloth without solvent.

It is also hard to get static electricity after dry wiping, and it is also a feature that it is difficult to get dust etc.

Surface is smooth, it is hard to scratch, there are also characteristics that it is difficult to attach water drops.
