Specification :
A sleek and versatile prime, the Sony E-mount AF 45mm f/1.8 FE from Samyang is a normal-length prime characterized by its compact design and bright f/1.8 maximum aperture. The optical design incorporates a pair of aspherical elements and one extra-low dispersion element, which help to suppress spherical and chromatic aberrations for improved sharpness, color accuracy, and clarity. An Ultra Multi-Coating has also been applied to reduce flare and ghosting in order to achieve higher contrast when working in strong lighting conditions. Additionally, the lens's linear STM autofocus motor works in conjunction with Sony cameras' AF systems for quick, quiet, and precise focusing performance, and manual focus override is also available for more refined control.
