This is an RF cinema lens from the CINE-SERVO lens series that provides improved compatibility with the new digital cinema camera, EOS C400. The CN7 X 17 KAS T maintains exceptional optical performance and mobility while incorporating the "new mount data communication system" unique to the EOS R system and a new drive unit to facilitate finely detailed operations. Enhanced technologies provide a broader range of shooting applications for virtual production and remote shooting.
Outstanding Optical Performance
Canon's optical technologies, such as the use of large-diameter aspherical lenses and anomalous dispersion glass, work together to deliver optical performance that is suitable for 8K cameras across the entire zoom range. Aberrations are minimized to ensure exceptional performance from the center of the image to the edges.
The Cinema Lens series is designed with a consistently warm colour balance that reproduces skin tones more beautifully to depict subject textures better. Colour reproduction remains stable even after changing lenses, reducing colour adjustment with each shot and time and effort for postproduction.
The 11-blade iris diaphragm creates a nearly circular bokeh from fully open to minimum aperture.
The odd number of iris blades results in a soft, diffused glow on high-brightness subjects.
The optical design of CN7 X 17 KAS T reduces focus breathing (changes in the angle of view due to the movement of focus position during focusing).
This enables consistent framing even during manual shooting.
Lens metadata communication via the mount is enabled with compatible Cinema EOS System RF cinema cameras. In addition to the same functions as previous models, it now offers support for in-camera distortion correction according to lens characteristics.
This advancement makes highly accurate real-time and post-production computer generate (CG) compositing possible.
Dual Pixel CMOS AF II together with the high-speed communication between the lens and camera allows acurate focusing in 4K recording.
Supports Focus Guide that provides visual aide to assist focusing:
Ambient light and chromatic aberration correction can be done in-camera with the lens information.
Lens information can displayed on the viewfinder and screen. Metadata such as lens name and position an also be recorded on the video.
The CN7 X 17 KAS T PL supports eXtended Data, which is offered by ZEISS as an extension of the Cooke /i Technology communications standard. When connected to the PL mount contacts of a compatible camera, it allows real-time output of lens information. This includes shading and distortion in real-time, as well as the recording and correction of information.
The CN7 X 17 KAS T PL supports Cooke's /i Technology communication standard. Connection to the PL mount contacts of a compatible camera enables real-time external output of lens metadata (focus/zoom/iris position and other data, model number) and recording and display of information.
The CN7 X 17 KAS T RF / PL supports 12-pin serial communication, which is the standard for broadcast camera systems. When connected to a compatible camera’s 12-pin connector, it enables the operation and control of the camera, similar to industry-standard portable lenses used in broadcasting.
The focus rings are equipped with gear pitches of 0.8 and 0.5. Specifically, the gear pitch in front of the focus ring is 0.8, and it is intentionally designed not to interfere with the follow focus, even if a drive unit is attached.
The focus ring markings and lines are placed on both the left and right sides. In addition, the focus indicators on the front end are engraved on an angled surface with larger text to ensure visibility from the side and behind.
Markings shows "ft" and "m".
The focus ring markings on one side have been coated with luminous paint to enhance visibility, ensuring clear and easy readability even in low light conditions.
