Product Introduction This is a F1.4 large-diameter, wide-angle lens that plays an active role in dimly lit rooms and places where the amount of light is insufficient. Adopting anti-reflective coating <SWC (Sub wavelength Structure Coating)>
with new technology to suppress flare and ghosting caused by light with a large incident angle that could not be prevented. From Discovery Japan ■
Aspherical lens Spherical aberration correction for large-aperture lenses, distortion aberration correction for wide-angle lenses, and zoom lens miniaturization. The aspheric lens was born 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. It is an optical material with low refraction and low dispersion, which is highly effective in removing secondary spectra. It has anomalous dispersion characteristics like fluorite, and the performance of two sheets is almost equal to that of one fluorite. ■
Ring USM USM (Ultrasonic Motor) = Ultrasonic motor with high torque / high response for quick focusing. It has ideal characteristics as a lens drive motor, such as almost no operating noise. ■
Rear focus A technology that reduces the total weight of moving lenses by using part of the lens configuration as a focus lens. Realizes high-speed, precise AF control, excellent holding balance, and compactness. ■
Full-time manual focus After auto-focusing, this function enables manual focus immediately by rotating the focus ring after one-shot AF so that the photographer can finally adjust the focus. ■
Dust-proof / Drip-proof The various parts have a highly dust-proof / drip-proof structure that can cope with the harsh shooting conditions of professionals to prevent the entry of dust and water droplets. ■
SWC (Subwavelength Structure Coating) Special coating SWC (Subwavelength Structure Coating) is a new type that suppresses light reflection by arranging countless 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.
