Marshall 5 mm to 50 mm f/1.4 CS-Mount Manual Focus Zoom Lens

The Marshall 5 mm to 50 mm f/1.4 Manual Focus Zoom Lens for CS Mount is designed to elevate surveillance performance with a versatile 10x optical zoom, a bright f/1.4 aperture, and precise manual controls. Built for CS-mount cameras, this compact, all-metal lens delivers sharp imagery across the entire zoom range, making it ideal for retail storefronts, corridors, parking lot surveillance, and other security setups where flexibility and clarity matter. This lens blends practical engineering with thoughtful design, prioritizing reliability, ease of use, and consistent image quality in demanding environments.

• Vast focal range with superb versatility. The 5 mm to 50 mm focal length covers a wide spectrum from broad scenes to close-in detail. With a 10x optical zoom, you can frame expansive entrances, aisles, or parking areas and quickly move to telephoto shots of far corners without swapping lenses. This flexibility reduces camera repositioning and equipment changes, helping security teams respond faster to unfolding events.
• Bright, low-light capability for clearer night surveillance. The fast maximum aperture of f/1.4 lets more light reach the sensor, improving performance in dim conditions and enabling crisper images when lighting is limited. This makes it easier to identify faces and license plates during nighttime monitoring or in shadowed indoor environments, while preserving image detail across the zoom range.
• Precise, reliable manual control for critical framing. This is a dedicated manual focus zoom lens, designed for operators who prefer tactile, precise adjustments. The manual zoom ring provides smooth, deliberate framing changes, and the manual focus ring allows fine-tuning for critical subject sharpness. By eliminating reliance on electronics for zoom, focus, or iris, it offers consistent behavior in varied conditions and reduces risk of electronic malfunctions in challenging environments.
• Rugged CS-mount compatibility in a compact form. Engineered specifically for CS-mount surveillance cameras, this lens fits seamlessly into standard CCTV and security deployments. Its compact, all-metal housing balances durability with discreet footprint, making it suitable for ceiling, wall, or pole-mounted installations where space is at a premium.
• High optical quality across the zoom range for dependable surveillance imagery. The lens is designed to deliver edge-to-edge sharpness with minimized distortion across its entire focal span. Coatings and optical elements are optimized to reduce flare and ghosting, producing consistent contrast and color fidelity whether the scene is a bright storefront or a dim corridor. This makes the Marshall lens a dependable choice for consistent monitoring streams and recorded footage.

how to install Marshall - 5 mm to 50 mmf/1.4 - Manual Focus Zoom Lens for CS Mount

Follow these general steps to install the lens on a CS-mount surveillance camera:

• Power off the camera and disconnect it from any power source before handling lenses to prevent electrical or static damage.
• Remove the existing lens from the CS mount and carefully inspect the mount surface for dust or debris. Use a clean, lint-free cloth if needed to ensure a clean seating plane.
• Align the Marshall lens with the CS mount and thread it onto the camera body by turning clockwise. Do not force the lens; if it resistance, stop and realign to avoid cross-threading. Allow the lens to seat securely without overtightening.
• Once mounted, switch the camera back on and view the live feed. Use the zoom ring to frame the scene at your preferred focal length, then rotate the focus ring to achieve sharp focus on the subject. Take note of critical focus distances at different zoom settings so you can quickly reacquire focus in dynamic environments.
• Fine-tune exposure and lighting within the camera's settings to maximize image quality. If infrared or low-light conditions are expected, verify focus accuracy at the operating wavelengths and adjust as necessary for reliable identification in surveillance footage.
