The Canon CN-E 14.5-60mm T2.6 L S Cinema Zoom lens with EF Mount is designed expressly for digital cinematography with cameras that have an APS-C or Super 35-equivalent sensor and a EF mount, including Canon's EOS C300. Featuring advanced Canon optical technology, the lens is suitable for any capturing any size HD image up to and including 4K resolution.Intended for the working professional, the CN-E14.5–60mm T2.6 L S lens has markings on angled surfaces on both sides of the barrel, making it easy to read settings from behind, or from either side of the camera. Focus markings can even be switched from standard labeling to metric, depending on production need. This lens is equipped with control rings maintain the proper amount of resistance with consistent operating torque, and a covered flange-back adjustment mechanism to meet numerous production application needs.Designed to fulfill contemporary 4K production standards, this phenomenal lens surpasses the performance requirements of any HD imaging system. It features advanced optical design with fluorite and large aspherical lens elements to achieve sharp, consistent images throughout their zoom range. Canon engineers also incorporated geared inner focusing to minimize focus-induced changes in the angle of view, reducing focus breathing virtually to zero. The 11-blade aperture diaphragm ensures smooth out-of-focus areas, while innovative glass construction counteracts barrel expansion and contraction to avoid temperature-induced marking discrepancies.
