Designed for portraiture, landscapes, and astrophotography, the AF 135mm f/1.8 FE from Samyang is a medium-length telephoto prime designed for full-frame Sony E-mount mirrorless cameras. Offering outstanding resolution, the optical design incorporates three extra-low dispersion elements and an ultra-precision aspherical element, which suppresses both chromatic and spherical aberrations for improved sharpness, color accuracy, and clarity. An ultra multicoating has also been applied to reduce ghosting and flare in order to achieve higher contrast when working in strong lighting conditions.
The lens has a linear STM autofocus motor for quick, quiet, and precise focusing performance, plus a minimum focusing distance of just 2.3" to suit working with close-up subjects. Three different customized buttons for enhanced functionality include a focus hold button, a custom switch, and a focus range limiter switch. It also features an astro-focus function for astrophotography. The weather-sealed construction offers protection against dust, light rain, and snow.
