4427B005AA
Style: Lens only Product introduction Spherical aberration correction for large-aperture lens, distortion aberration correction for wide-angle lens, miniaturization of zoom lens
Aspherical lenses were created to solve these three themes.
Ideal chromatic aberration correction with more lenses
The UD (Ultra Low Dispersion) lens was developed based on this theme.
USM (Ultrasonic Motor) = Ultrasonic motor with high torque / high response and quick focusing
It has ideal characteristics as a lens drive motor, such as almost no operating noise.
Features from Discovery Japan Minimum shooting distance 0.15m
Full-scale fisheye effect with 3 different image sensors (full-size fisheye and diagonal fisheye in full size)
The world's first fisheye lens that has realized a diagonal fisheye for APS-C / H size)
UD lens and high-precision GMo aspherical lens realize high resolution and high contrast image quality suitable for L lens
It has high dust / drip proof performance and durability.
* As an interchangeable lens for single-lens reflex cameras

・ Aspherical lens Correction of spherical aberration of large-aperture lens, distortion correction of wide-angle lens, miniaturization of zoom lens
Aspherical lenses were created to solve these three themes.

UD lens Ideal chromatic aberration correction with more lenses
The UD (Ultra Low Dispersion) lens was developed based on this theme.
An optical material with low refraction and low dispersion characteristics that is highly effective in removing secondary spectra. It has anomalous dispersion characteristics like fluorite, and two sheets have performance almost comparable to one fluorite.

-Ring USM USM (Ultrasonic Motor) = Ultrasonic motor is high torque / high response and supports quick focusing.
It has ideal characteristics as a lens drive motor, such as almost no operating noise.

・ Inner focus A part of the lens configuration is a focus lens, reducing the total weight of the moving lens.
Realizes high-speed, precise AF control, excellent holding balance, and compactness

・ Full-time manual focus After auto-focusing, manual focus can be performed immediately by rotating the focus ring after one-shot AF so that the photographer can finally adjust the focus.

・ Dust and drip-proof Highly dust- and drip-proof structure for various harsh shooting situations to prevent intrusion of dust and water droplets

・ SWC (Subwavelength Structure Coating) Special coating SWC (Subwavelength Structure Coating) is a new technology that suppresses light reflection by arranging innumerable nano-sized wedge-shaped structures smaller than the wavelength of visible light on the lens surface. Anti-reflection technology
Even with a wide-angle lens such as a wide-angle lens, it is possible to greatly reduce the occurrence of flares and ghosts in the periphery.

・ Fluorine coating New coating technology developed for the purpose of easily removing dirt adhering to the lens surface
That is fluorine coating
Oil and water repellency is high and can be removed with a dry cloth without using solvents.
It is also characterized by being less likely to be charged with static electricity after being wiped dry, and to keep dust away
The surface is smooth and not easily damaged, and there are also characteristics that prevent water droplets from sticking.
