Made just for mirror less cameras is the Rokinon 12mm T2.2 NCS CS Ultra Wide Angle Cine Lens. Its 35mm focal length equivalency for Sony E- Mount (NEX) Cameras is 18mm. With a T2.2 maximum aperture, it is particularly effective in low-light capture and can control shallow depth of field for precise subject focus with pleasing out-of-focus backgrounds. It offers a minimum focus distance of 7.9" and its front filter thread accepts 67mm size filters. The lens's impressive optical construction consists of three Extra-low Dispersion elements, one aspherical, and one hybrid aspherical element. The nano-crystal coating is applied to the inner surface of the two front-most lens elements to minimize ghosting and flare and improve overall image clarity. As a lens designed for shooting HD video, it offers features that differentiate it from "photo lenses," which, of course, can also serve to shoot HDSLR video. However, Rokinon Cine lenses have a clickless aperture ring, which is not only silent but enables smooth transitions between stops and the ability to shoot between those stops. Furthermore, it relates aperture in T-stops (Transmission-stops) which is a more accurate measurement of the light entering the lens that actually makes its way to the image sensor and is a more consistent measurement from lens to lens. Additionally, a Cine lens features geared aperture and focus rings to enable the use of focus pull apparatus such as a follow focus system.
