Rokinon 50mm T/1.5 Cine DS Lens (for Video DSLR Sony Alpha A-Mount Cameras) with:
Rokinon 50mm T/1.5 DS Cine Lens (for Sony Alpha A-Mount)
Optimized for shooting video.
The Rokinon 50mm T/1.5 AS UMC Cine DS Lens is a fast manual focus prime lens. It provides a very fast maximum aperture of T/1.5 for effective low light capture and shallow depth of field control, and an 8 blade iris for attractive bokeh. Optimized for cinema and video applications, the focus and aperture control rings are outfitted with industry standard gearing, which provides an interface for working with a traditional follow focus. The aperture control ring has also been de-clicked, which enables smooth iris pulls. In addition, bright aperture and distance markings are printed on the lens barrel facing laterally to facilitate easier control by a focus puller.
This 50mm lens has a minimum focus distance of 1.5 feet. Internal focusing minimizes the effects of lens breathing, which insures a more consistent angle-of-view when adjusting focus. The lens is composed of 9 elements in 6 groups, including one aspherical element and one hybrid aspherical element to reduce aberrations. In addition, a lens multi-coating helps to improve light transmission reducing flare and ghosting. The filter thread diameter is 77mm.
With this 50mm lens, Rokinon introduces the DS series of cinema lenses, unifying their cine lenses in more than just name. Each of the DS branded lenses will offer the same alignment of their geared focus and aperture rings so that follow focus and other rig accessories won't need re-adjustment when swapping lenses. Also, each DS lens is tested to be color matched with the other lenses in the series and provide the same color and contrast when shooting video. Lastly, the lenses are marked with focusing scales on each side of the barrel for easier adjustment from either side of the camera.
