A wide-angle prime lens featuring a compact design, the 35mm f/2S DF DSM Lens from Yongnuo is designed for full-frame format Sony E-mount mirrorless cameras. The lens's bright f/2.0 design suits working in low-light conditions and also enables increased control over depth of field for isolating subject matter. The optical design features an aspherical element, along with one high refractive index element, which significantly reduces spherical aberrations and distortion for increased clarity and definition for notably sharp image quality. It also features a low-dispersion glass element to suppress the dispersion problem caused by wide-angle lenses. Balancing the optics is a DSM autofocus system, which promotes fast and quiet focusing performance to suit both photo and video applications.
