The canon EF mount samyang 35mm f/1.4 AS UMC Lens is a prime standard
wide-angle lens designed for both full-frame and APS-C sized sensors; when used
with an APS-C sensor the 35mm-equivalent focal length is 56mm. It is
well-suited to working in a variety of situations ranging from landsCap,e to
portraiture. Its incredibly fast f/1.4 maximum aperture is further beneficial to working
in low-light conditions and for greater control over selective focus and
shallow depth of field effects. Two high refractive index elements and one
aspherical element have been incorporated into the optical design to minimise
chromatic aberrations in order to produce sharper images. A UMC coating has
also been applied to lens elements to reduce surface reflections and prevent
lens flare and ghosting for improved light transmission and more contrast-rich
imagery.
