The silver 12mm f/2.0 NCS CS Lens for Sony E-Mount (APS-C) from Samyang is a wide-angle prime lens designed specifically for use with APS-C format image sensors. Providing a 35mm-equivalent focal length of 18mm and a broad 98.9° angle of view, this lens is well-suited for architectural, interior, and landscape images. Its fast f/2.0 maximum aperture is beneficial to working in low-light conditions. Three extra-low dispersion elements, one hybrid aspherical element and an aspherical element reduce chromatic aberrations and distortions in order to produce sharper images from the center to the corner of the image frame. Nano Coating System improves light transmission and suppresses lens flare and ghosting for more contrast-rich, color-neutral images. A six-blade aperture closes to create a near full circle and the lenses minimum focus distance is 7.9". The lens barrel is built with aluminum alloy with a 67mm diameter filter thread and includes a removable petal-style lens hood.
