Canon CN-E 35mm T1.5 FP X Sumire Cinema Lens (PL Mount) The Sumire Prime Lens series features a nuanced look as the lens aperture approaches its maximum setting. This subtly modifies the textural renderings of the human facial close-up and a pleasing bokeh. The lens features a large-diameter aspheric lens and anomalous dispersion glass, for high-resolution image reproduction from the image center to the image edge. The lens produces warm color tones that help to softly capture facial expressions, and shares a unified color balance with other Canon Cinema lenses. The 11-blade clickless iris produces artistic and beautiful out-of-focus areas, creating a more three-dimensional bokeh. The use of an odd number of blades helps reduce flaring of specular highlights. The Sumire Prime Lens series features a unified front diameter (114mm), rotation angle (300°) and gear position on the focus and iris rings. The focus and iris rings are designed to maintain a consistent amount of resistance and operating torque in order to help provide the camera operator or assistant with predictable lens operation. Lens markings are displayed on both sides of the lens. To improve visibility in dim light conditions, indicator markings with phosphorescent paint have been adopted for the front barrel for right-side viewing. All lenses in the series except the 14mm accept a 105mm diameter threaded filter in the front of the lens.
