Optical Performance to Support 4K Cameras
CN-E20mm T1.5 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 C700 Digital
Cinema Camera, the CN-E20mm T1.5 L F will help you to create a cinematic
masterpiece by providing superb image quality, contrast and color fidelity.
High Resolution and Warm Colors
lens features a large diameter aspheric lens and anomalous dispersion glass,
working to deliver high contrast and sharp imaging from the center of the image
to the outer edges. This helps bring out the high quality of 4K cinema images.
The lens produces warm color tones that help to softly capture people’s facial
expressions and enable better depiction of textures captured through the lens.
Fast T Number
at T1.5 helps the lens achieve a softer and greater bokeh, while allowing users
to shoot brighter in low-light settings.
Warm Color Balance within Canon
Canon’s color science has become highly refined over
generations of lens designs, paying the closest attention to a pleasing skin
tone reproduction. The
CN-E20mm T1.5 L F lens can be used interchangeably with other Canon
Cinema lenses during the same production since they all have the same warm,
cine-look color characteristics — making it easier to maintain consistent color
when multiple lenses are used.
lens has been 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.
for Full-frame Cameras
CN-E20mm T1.5 L F Cinema Prime Lens covers 35mm full-frame sensor and features a genuine Canon EF mount and works with all Cinema EOS camera models, including full-frame models such as our new EOS C700 FF digital cinema camera, as well as other top-quality full-frame cameras. With a Super 35mm camera, the lens can be used as an approximately 29.2mm equivalent lens (35mm film equivalent) for use in a wide range of shooting situations, helping users produce premium-quality images.
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 CN-E20mm T1.5 L F
Cinema Prime Lens features an 11-blade iris. This produces artistic and
beautiful out-of-focus areas, creating a more three-dimensional bokeh with the
deeper depth of field that a super wide angle lens can offer, broadening
the range of visual expression. The use of an odd number of blades also helps
reduce flaring of specular highlights. Additionally, the iris ring is
mechanically controlled with no click stops for smooth exposure adjustments
Operability and Reliability
to meet the needs of professional cinematographers, the CN-E20mm T1.5 L F
Cinema Prime Lens features a unified front diameter (114mm), rotation angle
(300°) and gear position on the focus and iris rings (making lens switching
quick and convenient) across our entire Cinema Prime Lens series. The 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.
Front Lens Threading for Screw on Filters
To allow for additional
ease of use and flexibility, the lens features threading on the front of the
lens to accommodate 105mm screw on filters. This feature allows the camera
operator to add filters over the lens without the need for a matte box to
be attached to the camera system helping to provide flexibility in filter
choice as well as the ability to shoot in a more streamlined format.
lens is equipped with gaskets and seals for dust- and water-resistant operation,
helping to make them ready for shooting, even in severe conditions.
Visible Distance Indicators
indicators are displayed on both sides of the lens. To improve visibility in
nighttime and dark area shooting, indicator markings with phosphorescent paint
have been adopted for the front barrel (for right-side viewing).
Functions with Cinema EOS Cameras
CN-E20mm T1.5 L F Cinema Prime Lens works seamlessly with our Cinema EOS
cameras, allowing you to take full advantage of the camera’s features and
Information Display / Recording
information can be displayed on the viewfinder of the camera, and metadata such
as lens name and position can be recorded in the image.
Pixel Focus Guide
position data and Dual Pixel CMOS AF can combine to display the focus position
on the user interface.
