The Samyang AF 85mm f/1.4 FE II is a lightweight and compact short telephoto lens perfect for portraits and low-light situations because it combines cutting-edge optics with sophisticated handling. It accomplishes size and weight reduction in its second generation while enhancing optical and autofocus performance. It uses a series of high-refraction and extra-low dispersion elements to create a glass surface that produces smooth, cream-like bokeh. It has 11 optical elements, divided into 8 groups. The lens has a nine-bladed aperture diaphragm for the same purpose. An STM motor has been added to the autofocus system, which acquires subjects quickly and quietly and can be controlled in a variety of ways with the help of a programmable AF Lock button and focus ring. The entire metal body of the lens has full weather sealing to keep out moisture, dust, and other impurities. Prime normal-length lens is designed for full-frame Sony E-mount mirrorless cameras but can also be used with APS-C models where it will provide a 75mm equivalent focal length. Fully customizable focus ring and AF Lock buttons provide a new layer of controls, allowing you to tailor the lens exactly for your style of shooting Bright f/1.4 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques. Internal focus design along with weather sealing ensure dust and moisture resistance. The integrated autofocus motor works in conjunction with Sony cameras' focusing systems for quick, accurate, and precise AF control. Manual focus override is also available for refining your focus position. Nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
