The Samyang 50mm T1.5 Cine Lens (for Canon EF) is a fast manual focus prime lens. It provides a maximum aperture of T1.5 for low light capture and shallow depth of field control. Optimised for cinematography 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.
