AXIS Computar - 12.50 mm to 50 mm f/1.4 Telephoto Zoom Lens for CS Mount

This 12.5-50 mm telephoto zoom lens from AXIS Computar is engineered to elevate surveillance and machine vision with superb image quality and flexible focal range. Built to be compatible with CS-mount cameras, it delivers an impressive brightness and sharpness from edge to edge, making it ideal for color and day/night cameras in a wide range of applications—from perimeter security and traffic monitoring to factory automation and process control. The lens features an f/1.4 maximum aperture, IR-corrected optics, and both DC-iris and P-iris options, giving you precise exposure and consistent performance in varying lighting conditions. Its robust optical design provides a larger image circle, which translates to excellent corner clarity and minimal vignetting, ensuring you capture every detail across the entire frame. Designed for Megapixel sensors, this lens blends high resolution with smooth, distortion-free performance, making it a dependable choice for demanding surveillance and analytics tasks.

• Exceptional flexibility with a versatile 12.5-50 mm focal length and a fast f/1.4 aperture, delivering bright, visibility-rich images across a wide range of scenes—from wide-area surveillance to close-up zoom for detail capture. The telephoto zoom design minimizes distortion while maintaining sharpness across the image field, so you can rely on consistent image quality whether the subject is near or far. This lens is purpose-built for CS-mount cameras, enabling straightforward integration into existing security systems or machine-vision setups without complicated adapters.
• IR-corrected optics and Megapixel-ready performance ensure crisp, high-contrast images day and night. The IR-optimized design reduces ghosting and flare in night scenes, preserving color fidelity and tonal balance when infrared illumination is present. With support for both DC-iris and P-iris controls, you can choose precise iris management for stable exposure and depth of field in dynamically lit environments. The result is reliable autoexposure behavior and smooth iris adjustments that keep subjects clear from foreground to background, even as lighting changes.
• Megapixel-optimized image circle means you get high-resolution clarity across the entire frame, not just in the center. The large image circle minimizes corner softness and preserves edge-to-edge sharpness, which is critical for license plate recognition, facial capture, and other analytics tasks where detail matters. The lens design also reduces angular distortion and vignetting, helping your surveillance system produce uniform images that are easier to analyze with software and algorithms.
• Durable, camera-ready design tailored for rigorous surveillance environments. The zoom mechanism offers smooth, repeatable control for precise framing, while the robust construction supports long-term operation in demanding installations. Its compatibility with color and day/night cameras makes it a versatile choice for multi-camera deployments where a single lens model can cover varying scenes and lighting conditions, reducing inventory and maintenance complexity.
• Easy integration and practical installation considerations. The 12.5-50 mm zoom range provides rapid adaptation to changing scenes without swapping lenses, while the adjustable iris options let you tailor exposure to the scene, reducing the need for post-processing corrections. The lens supports precise manual focus and zoom control, ensuring operators can lock in the exact field of view required for monitoring, analytics, and detection tasks.

how to install AXIS Computar - 12.50 mm to 50 mm f/1.4 - Telephoto Zoom Lens for CS Mount

• Verify that your camera uses a CS-mount lens and that the lens thread matches your camera’s mounting interface. Power down the camera before installation to avoid any static or electrical issues.
• Remove the existing lens or protective cap from the camera housing. Check for any shims or brackets that may be part of your camera’s mounting system and set them aside as needed.
• Align the Computar lens with the camera’s CS-mount. Gently insert the lens and rotate it clockwise until it seats securely. Avoid overtightening to prevent damage to the threads or the lens mount.
• Attach any required locking screws or retaining rings if your camera kit includes them. Tighten evenly to ensure a stable, vibration-free attachment that preserves optical alignment during operation.
• Choose your iris control mode—DC-Iris or P-Iris. If using DC-Iris, connect the iris control cable to your auto-iris controller or compatible camera port; for P-Iris, configure the iris using the camera or controller software as specified in your system’s manual.
• Set the zoom and focus to your desired framing. Start with a wide focal length and gradually zoom in to frame the subject. Adjust focus for crisp detail across the scene, then fine-tune the iris to achieve optimal exposure given the lighting conditions.
• Test under the actual operating environment, including any infrared illumination if night surveillance is required. Confirm that exposure, brightness, and contrast meet your monitoring needs, and re-check focus at the final zoom level to ensure consistency.
• Lock any adjustable rings if your installation requires a fixed field of view. Document the installed configuration for future maintenance or lens replacement tasks.
