AXIS - 8-50 mm f/1.6 Telephoto Zoom Lens for CS Mount

This AXIS varifocal telephoto zoom lens is designed for high-clarity surveillance in professional security deployments. With an 8-50 mm focal range and a fast f/1.6 aperture, it delivers versatile framing from wide-angle to telephoto, enabling operators to capture critical details across varying distances without swapping lenses. Built for CS-mount cameras and optimized for up to 5 MP sensors, this lens is ideal for retail storefronts, parking facilities, corridors, lobbies, and outdoor environments where precise exposure control and image clarity matter most. The inclusion of P-Iris support ensures accurate iris control under rapidly changing lighting, delivering consistent exposures and sharp, repeatable results throughout the day and night. Whether you are upgrading an existing Axis system or equipping a new installation, this lens provides reliable performance, simple integration, and the flexibility to adapt to evolving surveillance needs.

• Versatile 8-50 mm focal range: Transition smoothly from wide views to close-up telephoto, enabling flexible coverage of entrances, aisles, checkpoints, and perimeters without lens swaps or reconfigurations.
• Bright F/1.6 aperture for enhanced low-light performance: Capture legible facial features, license plates, and fine textures in dim conditions, supporting clearer evidence and improved security outcomes after dark or in shaded areas.
• P-Iris support for precise exposure control: Maintain consistent brightness and contrast across scenes with changing illumination, ensuring highlights are preserved and shadows retain useful detail for reliable analytics and inspection.
• CS-mount compatibility with up to 5 MP sensors: Seamlessly integrates with AXIS and other CS-mount cameras that support high-resolution imaging, enabling sharp, distortion-minimized footage suitable for forensic review.
• Compact, robust design and easy installation: Engineered for professional environments, the lens reduces bulk while delivering dependable performance in both indoor and outdoor surveillance applications with long-term reliability.

How to Install AXIS - 8-50 mm f/1.6 Telephoto Zoom Lens for CS Mount

• Prepare the camera: Power down the camera system and ensure the mounting area is clean and free of debris. Verify that your CS-mount camera supports P-Iris control if you plan to utilize iris automation.
• Remove any existing lens: If the camera currently has a lens installed, carefully detach it by detaching the securing ring or screws as applicable to your model. Keep the screws in a safe place for reassembly.
• Attach the lens: Align the 4-pin CS-mount interface with the camera body’s CS-mount port. Gently screw the lens into place using a standard torque—avoid over-tightening to prevent thread damage. Ensure the lens is seated evenly.
• Secure and verify: Once the lens is mounted, secure any locking ring or fasteners per the camera’s mounting instructions. Confirm there is no play between the lens and camera to prevent image drift during operation.
• Configure focus, zoom, and iris: Power up the system and use the lens’ manual focus and zoom rings to frame the scene. If your camera supports P-Iris, enable P-Iris in the camera settings and adjust exposure to achieve balanced brightness across the scene. Perform a test run across the zoom range to verify sharpness and exposure stability from 8 mm to 50 mm.
• Fine-tune alignment and exposure: Check for barrel distortion, vignetting, or misalignment. Adjust the camera’s region-of-interest (ROI) or image processing settings if needed to optimize detail capture at the focal lengths most used in your installation.

Frequently asked questions

• Q: Is this lens compatible with all CS-mount cameras?
• A: The lens is designed for CS-mount cameras and is suitable for AXIS systems and other CS-mount models that support up to 5 MP sensors. Always verify that your camera supports P-Iris and the desired resolution before use.
• Q: Do I get better nighttime performance with the F/1.6 aperture?
• A: Yes. The bright F/1.6 aperture helps maximize light gathering, improving low-light sensitivity and enabling clearer details in nighttime scenes. Pairing with a camera that provides good low-light performance further enhances results.
• Q: What does P-Iris support mean for my installation?
• A: P-Iris allows the camera to automatically control iris size for precise exposure across a range of lighting conditions, delivering consistent image brightness and reducing the need for manual iris adjustments in dynamic environments.
• Q: Can this lens deliver sharp images across the entire 8-50 mm range?
• A: The varifocal design is optimized to maintain sharpness and detail across the zoom range, but optimal performance is achieved when properly focused at the selected focal length and when mounted on a camera configured for high-resolution output.
• Q: How do I verify sensor compatibility and lens performance?
• A: Check your camera’s supported resolution (up to 5 MP for this lens), confirm P-Iris capability if needed, and perform calibration tests at multiple focal lengths to ensure consistent focus, brightness, and distortion control in your installation.
