Canon CN-E30-300mm T2.95-3.7 L SP EF Cinema Zoom Lenses
The EF Cinema Zoom lens CN-E30-300mm T2.95-3.7 L SP (PL mount) rivals best-in-class zoom magnification and telephoto focal length for the Super 35mm format, and is engineered to offer unrivaled optical performance for demanding high-end productions, meeting and exceeding industry standards.
Intended for the working professional, the CN-E30-300mm T2.95-3.7 L SP 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 designed to 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.
