The CN-E 14mm T3.1 L F Cinema Prime Lens is 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 CN-E 14mm T3.1 L F will help you to create a cinematic masterpiece by providing superb image quality, contrast and color fidelity.
The CN-E 14mm T3.1 L F Cinema Prime Lenses features a genuine Canon EF mount and works 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 video file.
The use of an 11-blade iris produces artistic and beautiful out-of-focus areas or "Bokeh." The 11 blades allow for attractive circular blurring in out-of-focus regions, while the use of an odd number of blades help reduce flaring of specular highlights. Additionally, the iris ring is mechanically controller with no click stops for smooth exposure adjustments while recording.
Designed to meet the needs of professional cinematographers, the CN-E 14mm T3.1 L F Cinema Prime Lens features unified front lens diameters and gear positioning on the focus and iris rings making lens switching quick and convenient. Additionally, the Focus ring features 300° 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.
The CN-E 14mm T3.1 L F Cinema Prime Lens is equipped with gaskets and seals for dust and water resistant operation, helping to make them ready for shooting, even in severe conditions.
The CN-E 14mm T3.1 L F Cinema Prime Lens is 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.
