The clickless iris allows you to smoothly adjust your exposure during the shot. Built-in iris and focus gears follow industry standards, allowing you to work with optional follow focus units and lens gear motors. The SLR Magic Cine 35mm f/1.2 Lens supports cine-style shooting on Sony E-Mount cameras and Fujifilm X-mount cameras. It weighs in at around a pound and covers full-frame sensors with a fast f/1.2 maximum aperture for shallow depth of field. It features geared focus and aperture rings, a clickless iris that allows smooth aperture pulls, and a 13-bladed iris for a rounded aperture and pleasing bokeh. The lens is suitable for portrait, interiors, architectural, and landscape cinematography and photography. The front of the lens does not rotate as you focus the lens; this allows you to use optional polarizing filters or accessories such as clip-on matte boxes. It incorporates a 52mm filter thread diameter for using a variety of readily available optional lens accessories.
