The Rangefinder CINE Adapter is an optical device with integrated follow focus gears. When attached to a compatible taking lens, one could overide the focus control of the taking lens with the Rangefinder’s built-in focus ring. Provides calibrated focus markings from 3’6 ft (1.1M) to Infinity. Highly recommended for users wanting to have single focus capability on the SLR Magic Anamorphot series of adapters, currently 1.33x and 2x. Furthermore the Rangefinder CINE adapter can be placed on many taking lenses to offer those wanting to have "cinema like" manual focus capability on auto-focus lenses. Like many SLR Magic products, the Rangefinder CINE adapter is crafted using black anodised metal to the highest standard.
