6-60mm Manual Aperture CS Mount Lens for 1/3" CCTV Camera Systems

This manual aperture lens provides a versatile 10x optical zoom, ranging from a 6mm wide-angle to a 60mm telephoto focal length, making it suitable for surveillance applications where scene coverage and detail are both important. Designed with a CS mount, it is compatible with cameras using a 1/3" image sensor format. The lens offers full manual control over both aperture and focus, allowing installers and operators to make precise adjustments directly on the lens itself without relying on electronic systems. Its compact build, with a weight of just 118 grams, facilitates integration into various CCTV housing setups.

Features and Construction

This lens is built around its core optical and mechanical specifications, prioritising manual control and compatibility with common surveillance hardware.

Material and Build

The lens construction is defined by its physical measurements of 37mm in diameter, 68.7mm in length, and 34mm in height. Weighing 118 grams, it is a compact and relatively lightweight component designed for CCTV systems. The external finish is black. The build incorporates manual control rings for adjusting both the aperture and the focus, providing a direct mechanical interface for the user.

Size and Practical Fit

The lens is engineered for a 1/3" format image sensor, a common size in surveillance cameras. Its CS mount interface ensures direct physical compatibility with a wide range of CCTV camera bodies using this standard. The compact dimensions allow it to be used in discreet or space-constrained installations, such as within dome housings or compact bullet cameras, without adding significant bulk.

Uses and Placement

With its variable focal length and manual controls, this lens is suited to environments where fixed-focus or motorised lenses are not required or desired.

Event or Professional Use

In professional surveillance, the 6-60mm range allows a single camera to cover a wide area at 6mm (44° field of view) and then zoom in to identify details at 60mm (4.58° field of view). This makes it applicable for monitoring perimeters, car parks, or retail spaces where both overview and identification are needed. The manual controls allow settings to be locked in for consistent performance in fixed lighting conditions.

Everyday Home Use

For residential security systems, this lens can be used in a main entryway or garden camera. The wide 6mm setting provides a broad view of a driveway or patio, while the ability to manually zoom to 60mm allows for closer observation of a specific door or gate. The f/1.6 aperture assists in maintaining image quality during dusk or dawn hours without requiring additional IR illumination in all scenarios.

Benefits and Buying Value

The value of this lens lies in its optical flexibility, direct control, and standardised compatibility for surveillance applications.

Reuse and Low Maintenance

As a purely mechanical and optical component with no internal motors or electronics, the lens has fewer potential points of failure compared to motorised variants. This can contribute to a longer service life within a CCTV system. Its standard CS mount and 1/3" format mean it can be reused or swapped between compatible cameras if a system is upgraded or reconfigured.

Why Choose This Product

This lens is a practical choice for users who need optical zoom capability but do not require, or wish to avoid, the cost and complexity of motorised zoom control. The manual operation provides a reliable, set-and-forget solution for fixed surveillance scenarios. The combination of a 10x zoom ratio, a fast f/1.6 aperture, and a 0.3m minimum focus distance offers a balanced specification for general monitoring tasks.
