Product introduction

Responding to the needs of architectural photographers, it realizes super low distortion and high image quality to the periphery of the screen.

In addition to high optical performance using large aperture aspherical lenses and UD lenses, new anti-reflective coating SWC (Subwavelength Structure Coating) suppresses the occurrence of flare and ghost due to light with a large incident angle.

It also pursues comfortable operability such as TS revolving function which can set the movement direction of tilt and shift from 0 to 90 ° from direct to parallel and adoption of large knob.

In addition, it is equipped with a tilt lock mechanism that securely fixes the tilt section at the reference position.

Features

Responding to the needs of architectural photographers, it realizes super low distortion and high image quality to the periphery of the screen.

In addition to high optical performance using large aperture aspheric lenses and UD lenses, new antireflection coating SWC (Subwavelength Structure Coating) suppresses the occurrence of flare and ghost due to light with a large incidence angle.

We also pursued comfortable operability such as the TS revolving function which can set the movement direction of tilt and shift from 0 to 90 ° from direct to parallel, adoption of large knob and so on.

In addition, it is equipped with a tilt lock mechanism that securely fixes the tilt section at the reference position.

Aspherical 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.

To detail

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.

To detail

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.
