==== Summary ====
Sumire, pronounced "Soo-mee-ray", is the name of a Japanese flower, and like the petals of a flower, our lenses are most beautiful when fully opened. This is the inspiration behind the Sumire look. The Sumire Prime CN-E 14mm T3.1 FP X lens offers a compact, consistent lens design and proven Canon lens elements for performance and reliability in professional shooting environments. Intended for the working professional, Sumire Prime CN-E 14mm T3.1 FP X lens has markings on angled surfaces on both sides of the barrel, making it easy to read focus and aperture settings from behind or from either side of the camera. Focus markings can even be switched from standard labeling to metric. The control rings are engineered to maintain the proper amount of resistance with consistent operating torque.

Designed to fulfill contemporary 4K production standards, it features a full-frame imaging circle in a lightweight, compact design. This phenomenal lens is also perfect for any number of applications. It also features an 11-blade aperture diaphragm for beautiful background blur and innovative glass construction that counteracts barrel expansion and contraction to avoid temperature induced marking discrepancies. Canon's brilliant Sumire Prime lenses offer spectacular optical performance for demanding high-end productions. Sharing the same gear position, front diameter and rotation angle, the lenses' compatibility with third-party accessories allows crews to easily change lenses without making adjustments to the rig setup. Perfect on the EOS C700 FF, these lenses are designed for use with the latest full-frame and Super 35mm PL-mount cameras from leading manufacturers.
