The Nikon F mount Rokinon 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 52.5mm. It is well-suited to working in a variety of situations
ranging from landscape to portraiture. Its 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 minimize 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
This lens also incorporates an AE microprocessor that
enables the camera to electronically confirm focus as well as permit
camera-based control over exposure settings.
