The Canon CN-E Cinema Prime (EF mount) lens offers a compact, consistent lens design and proven Canon lens elements for performance and reliability in professional shooting environments. Canon EF Cinema Prime Lenses were developed to support high-end digital motion imaging. Sharing the same gear position, diameter and rotation angle, and front diameter, the Cinema Prime’s compatibility with third-party accessories allows crews to easily change lenses without making adjustments to the rig. Ideal for use on the EOS C300, these lenses are also compatible with all Canon EOS DSLRs.

Intended for the working professional, the Cinema Prime has markings on angled surfaces on both sides of the barrel, making it easy to read focus and aperture settings from either side or behind the camera. Focus markings can be changed from imperial 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, Cinema Primes features a full-frame imaging circle in a lightweight, compact design. This lens features an 11-blade aperture diaphragm with beautiful bokeh, and innovative optical construction which counteracts barrel expansion and contraction to avoid temperature-induced marking discrepancies. These compact, lightweight lenses were designed to meet the optical requirements for emerging 4K digital production image formats (from both ITU and SMPTE).

4K Ready

Cinema Primes are designed to provide outstanding optical performance and is capable of full 4K-Resolution performance. Whether you're shooting in HD with a Canon EOS DSLR camera or in 4K using an EOS C500 Digital Cinema Camera, the Cinema Prime will help you to create a cinematic masterpiece by providing superb image quality, contrast and color fidelity.

EF Mount

Cinema Primes feature a genuine Canon EF mount and are compatible with all Cinema EOS camera models, as well as all EOS HD-DSLR cameras, including Full-Frame models. The EF mount has electronic contacts on both the lens and camera sides that allow direct communication between each device. This communication allows lens metadata including T-numbers to be displayed in the viewfinder. Both the T-number and the focus position are recorded in the metadata.

Attractive Bokeh

The use of an 11-blade iris produces artistic and beautiful out-of-focus areas (i.e., bokeh). The 11-blade design enables attractive, circular background blurring, and the use of an odd number of blades helps reduce flaring of specular highlights. Additionally, the iris ring is mechanically controlled with no click stops, ensuring smooth exposure adjustments while recording.

Designed for Cinema

Designed to meet the needs of professional cinematographers, Cinema Primes feature unified front lens diameters and gear positioning on the focus and iris rings making lens switching quick and convenient. Additionally, the Focus ring features 300º of smooth rotation to help facilitate consistently accurate focusing especially when pulling focus during a shot. Control rings work to maintain the right amount of resistance and operating torque in order to help provide the camera operator or assistant with a consistent feel and predictable lens operation.

Dust & Water-Resistant

Each Cinema Prime is equipped with gaskets and seals for dust and water-resistant operation, ideal for shooting even in severe conditions.

Minimized Focus Breathing

Cinema Primes are designed to minimize variations in the angle of view while focusing, a phenomenon known as focus breathing. This feature is extremely important while focus pulling, where changes in the angle of view due to focus breathing could become apparent to the viewer.

Features:

• Marked focus rings can be switched from metric to imperial scale
• Uniform gear positions and front diameter eliminate the need for accessory gear position adjustment when switching lenses
• Cinema Prime lenses give distinctive resistance and feedback for satisfying manual control of focus and iris
• Minimizes focus-induced changes in the angle of view
• Compatible with industry standard accessories such as 0.8 pitch follow focus gearing and matteboxes
