The Samyang AF 135mm F1.8 FE is lighter than other 135mm lenses compatible with full-frame Sony FE mount. An optimum resolution is achieved through the optical design of 6 special glasses(3 ED, 2 HR, and 1 U-ASP) among 13 elements in 11 groups. Three extra low-dispersion lenses (ED) produce clear image quality effectively controlling chromatic aberration. The AF 135mm F1.8 FE uses a large-diameter aperture to provide smooth background blur.it is equipped with UA(Ultra-precision Aspherical) lens, so you can enjoy the natural and refined bokeh. Although it is a 135mm telephoto lens that effectively controls aberration at all focusing distances has made it possible to achieve a minimum focus distance of just 0.69 meters (2.26 ft) and a maximum magnification of 0.243x for close-up photography. Tracking the subject accurately and quickly, the AF also operates quietly and smoothly when shooting video. Samyang’s Linear STM (Stepping Motor) satisfies both photographers and videographers with quieter and more accurate control of the focusing lens groups.
