Yongnuo 35mm f/1.4 Standard Wide-Angle Prime Full Frame Wide-angle Prime Lens  (Black, 35 mm)

An especially fast wide-angle lens, the Canon EF-mount YN 35mm f/1.4 from Yongnuo pairs the comfortably wide field of view with a bright f/1.4 maximum aperture to suit working in difficult lighting conditions. The optical design incorporates two aspherical elements, which reduce spherical aberrations and distortion, and two low dispersion elements, which minimize chromatic aberrations and color fringing, and individual elements also feature a multi-layer coating to suppress flare and ghosting for improved contrast and color accuracy. A DC motor affords quick and accurate autofocus performance and a switch lets you quickly change from AF and MF focusing methods. Additionally, a micro-USB port is integrated in the lens design to permit installing firmware updates. Wide-angle prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 56mm equivalent focal length. Fast f/1.4 maximum aperture affords a great deal of control over depth of field for isolating subjects and using selective focus, and also benefits working in low-light conditions. Two aspherical elements help to minimize distortion and spherical aberrations for greater sharpness and accurate subject rendering. Two low dispersion elements are used to reduce color fringing and chromatic aberrations in order to achieve greater color accuracy and clarity. Individual glass elements feature a multi-layer coating to resist flare and ghosting for improved contrast and color fidelity. A DC motor is used for quick and accurate autofocus performance, and a dedicated switch lets you quickly change from AF to MF control. A focus distance scale is also featured to aid with pre-focusing techniques. Chrome-plated metal lens mount is durable and accurate for a secure fit with the camera body, and gold-plated contacts help to ensure consistent communication between the lens and camera. Seven-blade diaphragm contributes to a smooth bokeh quality. A micro-USB port is incorporated for updating the lens's firmware.
