The Rokinon AF 24mm F2.8 compact lens is the newest addition to rokinon?s series of highly popular full frame auto focus lenses for Sony E mount cameras. This 24mm offers outstanding image quality, a wider view than the Rokinon 35mm F2.8, and a fast and quiet auto focus system. The new Rokinon 24mm F2.8 lens was designed specifically for Sony full frame mirrorless cameras with a focus on three main features: optical quality, portability, and silent autofocus. Thanks to advanced manufacturing techniques, Rokinon now offers a wider angle view without sacrificing quality or performance. Optically, the lens is made up of 7 elements in 7 groups. Its construction has been optimally arranged for portability and to deliver high resolution from the center to the corners of the image. 3 aspherical/2 high refractive Index elements and rokinon?s Ultra multi-coating techniques are utilized to minimize chromatic aberrations and unnecessary light dispersion. Quiet, fast and accurate auto focusing make this lens perfect for stealthy street shooting. Its weight of just about 3.3oz and its inconspicuous size make it ideal for travel. A minimum focusing distance of 9.5? and a substantial wide angle of view will make this Rokinon full frame lens the go to lens for astrophotography and landscape photography. For the Sony Alpha a6000/a5000 series or other Sony APS-C cameras, the lens is equivalent to approximately 36mm, providing the same features with a more moderate wide angle of view.
