Samyang AF 14mm f/2.8 Lens for Canon EF is a bright ultra-wide prime characterized by its autofocus design and immense field of view. The optical design features one extra-low dispersion element, two aspherical elements, and four high refractive index elements, which help to reduce a variety of aberrations and distortions for greater sharpness, clarity, and color rendering. An Ultra Multi-Coating has also been applied to individual elements to suppress lens flare and ghosting for improved contrast when working in strong lighting conditions. Complementing the optical design, the autofocus system makes use of a lightweight focusing group for quick and quiet performance that benefits both photo and video applications. Additionally, the lens also has an all-metal housing and is weather-sealed for use in inclement weather conditions.
- Ultra wide-angle prime is designed for full-frame-format Canon EF-mount DSLRs, however, can also be used with APS-C models where it provides a 22.6mm equivalent focal length.
- Bright f/2.8 maximum aperture is well-suited to working in challenging lighting conditions and benefits astrophotography applications.
- One extra-low dispersion element helps to reduce color fringing and chromatic aberrations for notable clarity and color accuracy.
- Two aspherical and four high refractive index elements minimize distortion and spherical aberrations to achieve high sharpness and accurate rendering.
- An Ultra Multi-Coating has been applied to individual elements to reduce flare and ghosting for increased contrast and a neutral color balance.
- Rounded, seven-blade diaphragm contributes to a pleasing bokeh quality.
