The Samyang AF 12mm f/2.0 RF-S Ultra-Wide Angle Prime Lens is designed for Canon RF-S mount cameras, offering exceptional sharpness and minimal optical flaws for wide, immersive shots. With a 12mm focal length and wide f/2.0 aperture, this compact and lightweight lens is perfect for landscape, architecture, and night photography. Its autofocus system quickly and quietly tracks subjects, while the Linear STM motor ensures precise, near-silent focusing. The lens features three extra-low dispersion (ED) elements and two aspherical lenses to minimize chromatic aberration, distortion, and other optical imperfections. The 7-blade aperture creates smooth bokeh and star-burst effects in bright light sources. The lens has a minimum focusing distance of 0.2 meters (about 8 inches) and a magnification ratio of x0.09, making it ideal for close-up shots with a dynamic perspective. The lens is constructed with 12 elements in 10 groups, has a filter size of 62mm, and measures 2.25 inches in length, weighing 7.5 ounces. It is compatible with Canon RF-S mount cameras and features weather sealing for added durability.
