Rokinon 12mm f/2.0 Ultra Wide Angle Lens for Sony-E Mount
Rokinon's 12mm f/2.0 Ultra Wide-Angle Lens is a powerful prime wide-angle lens uniquely engineered for use with APS-C sized image sensors. It offers a 35mm equivalent focal length of 18mm and its broad angle of view makes it the perfect choice for architectural or interior imaging.
This lens creates a 98.9 degree angle of view, a 7.87-inch minimum focusing distance and accepts 67mm filters.
Owing to a large aperture range of f/2.0, the lens is a useful shooting device and delivers high image quality even in poor lightning conditions.
12 Element / 10 Group Optical Design
The optical construction of the lens comprises 12 elements divided into 10 groups, these components include one aspherical lens (ASP) and one hybrid aspherical lens (H-ASP). There are also three lenses made of ED glass with extremely low dispersion factor.
Nano Coating System (NCS)
This coating has been applied to the lens elements in order to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.
Aspherical Elements
Rokinon's aspherical lens design creates a more complex surface profile, while also reducing lens size and weight. Specially shaped aspherical elements near the diaphragm restore alignment of light rays at the image plane, translating to high sharpness and contrast even at maximum aperture.
The design further ensures consistent imaging performance throughout the entire focal range, while delivering incredible sharpness up to the periphery of the image.
Extra Low Dispersion Glass (ED)
Rokinon's Extra Low Dispersion glass technology is engineered to reduce chromatic aberrations, which becomes more of a problem as focal lengths get longer. By eliminating the tendency of light of different colors to focus to different points at the image plane.
This means your images will come out crisp and clear, with less of a chance of defracting light into an unwanted rainbow of colors so you can capture the images you want without any flare or blur.
