This RF cinema lens is ideal for users seeking a cinematic expression with a large-format camera in both live settings (sports, reporting, etc.) and creative uses (dramas, documentaries, etc.). An ultra-wide-angle focal length allows for capturing challenging images with large-format sensors, providing a practical solution for diverse live productions and virtual production in limited spaces.
The 11-55mm is the widest focal length in the CINE-SERVO lens series.
Widest Angle in the CINE-SERVO Lens Series
The CN5 x 11 IAS T (RF/PL) offers an impressive 11mm focal length, providing an ultra-wide angle of over 100-degrees at the wide end. This feature is ideal for capturing wide-angle shots with a strong sense of depth, especially in situations where getting close to the subject is challenging, the camera position is fixed, or an overhead shot is necessary.
Closest shooting distance (0.6 m): 74.2 x 39.1 cm.
*With a horizontal angle of view at the wide end, aspect ratio 1.9:1, screen size 26.2 x 13.8 mm.
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 minimised 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 CN5 x 11 IAS T (RF/PL) 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 CN5 x 11 IAS T PL supports eXtended Data, which is an extension of the Cooke /i Technology communications standard offered by ZEISS. When connected to the PL mount contacts of a compatible camera, this feature enables the real-time output of lens information. This includes real-time data on shading and distortion, as well as the capability to record and correct this information.
The CN5 x 11 IAS T PL is compatible with Cooke's /i Technology communication standard. Connecting to the PL mount contacts of a compatible camera enables real-time external output of lens metadata, including focus, zoom, iris position, model number, and other relevant data. This allows for the recording and display of essential information.
The CN5 x 11 IAS 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 allows for the operation and control of the camera, similar to the industry-standard portable lenses used in broadcasting.
CN5 x 11 IAS T (RF/PL) supports the Canon Virtual Production System. It communicates and calculates lens and camera information in real time, making it possible to retrieve CV metadata with a single Ethernet cable for recording. No prior calibration is required, and distortion data is delivered in tandem with zoom and other lens operations, allowing users to easily obtain more natural CG-composited images that match and coordinate with the shooting ranges of the real camerawork and the virtual space.
The RF mount’s high-speed 12-pin connection delivers real-time metadata output. Zoom, focus, and iris data are transmitted directly to the camera, processed instantly, and output via plugin as CV metadata — enabling natural CG composites that align seamlessly with real camerawork.
Canon’s Plug and Play system simplifies setup by syncing lens and camera metadata with a single Ethernet cable, eliminating the need for calibration.
This reduces equipment and preparation time, allowing creators to focus fully on their production.
Continuous distortion data, synced with zoom, ensures smooth integration between live images and CG.
Misalignment at the borders is eliminated for more natural composites, while zoom control provides added flexibility in framing and composition.
Minimum Object Distance (MOD)
Minimum Object Distance (MOD) Definition
MOD values are defined differently for broadcast and cinema lenses. Although the CN5 x 11 IAS T (RF/PL) and CJ15ex4.3B list different MOD figures on their specification sheets, they both deliver about the same working distance in practice.
