The Rokinon AF 24mm f/2.8 Sony E-Mount Compact Full Frame Wide-angle Lens was designed specifically for Sony full-frame mirrorless cameras with a focus on three features: optical quality, portability and silent autofocus. Optically, the lens is made up of 7 elements in 7 groups that have been optimally arranged for portability and to deliver high resolution from the center to the corners of the image. Three aspherical plus two high refractive index elements and Rokinon's Ultra Multi-Coating techniques are utilized to minimize chromatic aberrations and unnecessary light dispersion. Autofocusing is quiet, fast and accurate and a manual focus override allows for more refined control when necessary. Weighing only about 3.3oz and its inconspicuous size make it ideal for travel and perfect for stealthy street shooting. Additional features include a minimum focusing distance of 9.5" and an internal focusing design that prevents the front of the lens from rotating for easy use of polarizers. For the Sony Alpha a6000/a5000 series or other Sony APS-C cameras, its 24mm focal length is equivalent to approximately 36mm, providing the same features with a more moderate wide angle of view. The Rokinon AF 24mm F2.8 for Sony E comes equipped with a reversible lens hood, lens caps and a custom fitted case.
