Wide-angle 35mm f/1.2 prime is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it will provide a 56mm equivalent focal length. Fast f/1.2 maximum aperture offers a high degree of control over depth of field for working with selective focus and shallow depth of field techniques. Additionally, it also benefits working in low-light conditions with slower shutter speeds. Two aspherical elements and three high refractive index elements are featured in the optical design to control spherical aberrations and distortion for improved sharpness throughout the aperture range. One extra-low dispersion element is used to reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy. An Ultra Multi-Coating has been applied to individual elements to minimize ghosting and flare for increased contrast and color neutrality when working in strong lighting conditions. Manual focus design permits working with subjects as close as 1.1' away. Nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. Aluminum-alloy housing is both durable and lightweight. Rear contacts afford full camera-based control over exposure settings and also relay Exif data between the lens and camera body.
