The lenses are designed for cine-style production and feature a T2.1 to T16 aperture range and cover full-frame sensors with a 43.27mm image circle. The lenses have built-in 0.8 Mod focus and iris gears so each lens is compatible with standard cine-style lens accessories. Cine-style focus and iris gears and an internal focus design enable you to pull focus without the length of the lens changing, suiting this lens for use with rod-mounted accessories and matte boxes. The APO MicroPrime Cine lenses feature 150° of focus rotation, a common 85mm front diameter that eliminates the need for multiple matte box adapter rings. It incorporates an 82mm filter thread diameter for using a variety of readily available optional lens accessories.
