Manual Aperture CCTV Lens with 6-60mm Focal Length and CS Mount

This manual aperture and focus camera lens provides a functional 6-60mm focal length range specifically engineered for security and surveillance applications. Compatible with cameras using the CS lens mount and a 1/3-inch image sensor format, it offers operators direct control over image capture parameters. The lens's construction centres on delivering adjustable scene coverage, from a 44-degree wide-angle view to a narrow 4.58-degree telephoto perspective, making it a practical choice for fixed installations where monitoring distances vary. Its manual operation paradigm means settings are adjusted physically on the lens itself, providing a tactile interface for fine-tuning image clarity and light intake based on environmental conditions.

Features and Construction

The lens's core functionality is built around its adjustable specifications and mechanical controls, designed for integration into professional monitoring systems.

Focal Range and View

The 6-60mm focal length is the primary operational feature, enabling the camera's field of view to be adjusted significantly. At its widest 6mm setting, it provides a 44-degree angular field of view, suitable for covering broad areas like car parks or room interiors. When adjusted to its maximum 60mm focal length, the field of view narrows to 4.58 degrees, allowing for detailed observation of specific, distant points of interest. This range offers practical versatility without requiring a lens change, accommodating scenarios where both overview and detail capture are needed from a single fixed camera position.

Manual Controls and Specifications

Both the aperture and focus mechanisms are manually operated via rings on the lens barrel. The aperture features a ratio of 1:1.6, governing the amount of light entering the lens. The focus can be adjusted down to a minimum object distance of 0.3 metres, allowing subjects relatively close to the lens to be brought into clear focus. These manual controls provide the operator with direct, on-lens adjustment capabilities, which can be preferable in installations where environmental lighting or subject distance is consistent, or where automated systems are not required.

Uses and Placement

Its specification set defines clear application boundaries, making it suitable for particular professional environments and less suited for others.

Professional Security and Monitoring

This lens is fundamentally designed for closed-circuit television (CCTV) and security system integration. The CS-mount interface and 1/3-inch sensor format compatibility align with common professional and industrial camera bodies. Its manual operation suits controlled environments like industrial monitoring, traffic observation, or building perimeter security, where initial setup and calibration are performed by an installer, and frequent adjustments are not necessary. The ability to zoom from a wide scene to a specific detail makes it applicable for overview-and-detail applications from a single camera point.

Limitations for Casual or Automated Use

The lack of motorised controls for aperture, zoom, or focus means it is not suitable for applications requiring remote adjustment, automated tracking, or integration with advanced analytics software that demands electronic control. Its manual nature also makes it less ideal for environments where lighting conditions change rapidly and require constant automatic adjustment, or for installations where physical access to the lens for tuning is difficult after initial setup. It serves a specific niche within the broader surveillance market.

Benefits and Buying Value

The value proposition of this lens is anchored in its straightforward specification and the control it offers for compatible systems.

Simplicity and Direct Control

For system integrators or installers who prefer or require manual fine-tuning of image parameters, this lens provides a direct, uncomplicated interface. The absence of electronic components for focus or aperture can translate to a simpler integration process and potentially fewer points of failure in the control chain, assuming the physical mechanisms are robust. This can be a benefit in cost-sensitive or reliability-focused professional installations where the initial setup is performed meticulously and operational parameters remain stable thereafter.

Why Choose This Product

This lens is a logical choice when the primary requirement is a manually adjustable zoom lens for a CS-mount camera with a 1/3-inch sensor, particularly where budget constraints or system simplicity are considerations. Its compact size (37mm x 68.7mm x 34mm) and light weight (118 grams) facilitate installation in space-limited housings or on compact camera bodies. Buyers should select this lens specifically for its stated manual controls and focal range, ensuring their camera system uses a CS mount and requires a lens compatible with a 1/3-inch sensor format to achieve the intended field of view.
