AXIS - 8-26 mm f/0.9 Zoom Lens for CS Mount

Meet a high-performance varifocal lens crafted for demanding security deployments. The AXIS 8-26 mm f/0.9 Zoom Lens for CS Mount combines an ultrafast F/0.9 aperture with a versatile 8-26 mm focal range to deliver bright, detailed imagery across a wide range of scenes. Designed for 2 MP surveillance systems, this lens excels in low-light environments, maintaining crisp edges, accurate color, and smooth exposure as lighting shifts from daylight to dusk. Its DC iris provides precise exposure control, while the CS-mount interface ensures quick, secure integration with Axis cameras and compatible third-party models. Whether you’re monitoring entryways, storefronts, parking lots, or street-level corridors, this lens gives you the flexibility to frame scenes exactly as needed without swapping optics.

• Unmatched low-light performance: The fast F/0.9 aperture maximizes light intake, helping to reduce motion blur and noise in dim settings. This makes faces, license plates, and subtle textures easier to discern even when ambient light is scarce, while preserving color fidelity and detail essential for reliable identification.
• Varifocal flexibility for dynamic scenes: With an 8-26 mm focal range, you can quickly adapt your field of view from wide coverage to tight detail without re-mounting a lens. This flexibility is ideal for entrances, reception areas, parking zones, and aisles where camera position cannot be easily adjusted after installation.
• DC iris for precise exposure control: The DC-iris mechanism provides reliable, controllable exposure across the lens’s zoom range. When paired with compatible cameras, you can leverage automatic iris control for changing scenes or opt for manual iris adjustments to maintain consistent brightness in challenging lighting contrasts.
• CS-mount compatibility for streamlined deployment: The standard CS mount enables straightforward integration with Axis cameras and many other CS-mount units. Its sturdy construction and secure mounting facilitate dependable performance in busy environments, with minimal alignment effort during installation.
• 2 MP imaging compatibility and image quality focus: While the lens itself supports high-quality optical performance, it is designed to complement 2 MP surveillance systems, delivering sharp, high-contrast imagery across the zoom range. Expect improved edge definition, accurate texture rendition, and dependable performance for analytics and human recognition in typical 1080p workflows.

How to install AXIS - 8-26 mm f/0.9 Zoom Lens for CS Mount

Installing the AXIS 8-26 mm f/0.9 Zoom Lens on a CS-mount camera is a straightforward process that can elevate your security imagery with minimal downtime. Follow these guidance-rich steps to ensure a secure fit and optimal image quality:

• Prepare the camera and workspace: Power down the camera and disconnect power to prevent static or electrical issues during installation. Clear the mounting area to provide ample room for aligning the lens with the camera’s CS-mount.
• Remove the existing lens (if present): If your camera already has a lens installed, carefully detach it following the manufacturer’s guidance, keeping any protective shrouds or screws in a safe place for reuse if needed.
• Clean the CS-mount interface: Use a lint-free cloth to wipe the CS-mount threads and surrounding areas. Removing dust or oil helps ensure a clean seal and accurate alignment for optimal image quality.
• Attach the AXIS lens: Align the lens with the camera’s CS-mount and thread it in by hand until it seats snugly. Avoid overtightening, which could strain the mount or misalign the optics. If your installation requires, use a suitable tool to snug the lens without overtightening.
• Set the zoom and focus: Rotate the zoom ring to select your preferred focal length within the 8-26 mm range. Then use the focus ring to achieve a sharp image at the chosen setting. For quick deployments, start at a mid-range focal length (around 14-18 mm) and adjust as needed based on scene width and subject distance.
• Configure iris and exposure: Use the DC iris to adjust exposure, ensuring the scene remains well-lit without clipping highlights. If your camera supports auto iris control, enable it to let the system maintain balanced brightness as lighting varies; otherwise, set a manual iris to suit the environment.
• Test and fine-tune: View live footage from the camera and verify that the scene framing and exposure remain consistent as you sweep from wide to telephoto settings. Make minor adjustments to focus, iris, and exposure to optimize image quality across the lens’s range.
• Secure and document: Once satisfied with the setup, tighten all mounting hardware to prevent drift and document the focal length and iris settings for future reference, particularly in multi-camera deployments or changes in environmental lighting.
