The Samyang 35mm f/1.4 AF II is a versatile, well-rounded, wide-angle lens for Sony E-mount cameras. It excels in everything from street photography to landscape and video work, thanks to its suite of cutting-edge features, full-frame coverage, and customizable controls. Its updated AF system features an internal focusing design that maintains the overall length of the lens during use and prevents the filter ring and lens barrel from rotating during focusing. This benefits working with circular polarizers and graduated ND filters. A linear stepping motor is used for silent and precise operation. The built-in switch allows you to use the focus ring to control the aperture and features a full-time focus override. Making deliberate use of their ultra multicoating technology, Samyang has equipped this lens with two high refractive index elements and two aspherical elements to help control spherical aberrations and distortions for improved sharpness, resolution, and clarity. The physical design features weather-sealed construction to guard against dust and moisture. A rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
