The APO MicroPrime Cine 50mm T2.1 Lens from SLR Magic offers apochromatic capture in a lighter-weight, cine-style form. With a 46mm image circle projection, this wider Canon EF-mount lens is suitable for use with 8K cameras with high-resolution full-frame sensors. Its apochromatic elements are designed to correct color aberrations often seen in high-contrast images or shots captured with wide-open apertures.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 Degree of focus rotation, a common 85mm front diameter that eliminates the need for multiple matte box adapter rings, and an internal 82mm filter thread.
