6-60mm Manual Varifocal Lens with f/1.6 Aperture for 1/3-inch Sensor Cameras

This manual varifocal lens offers a versatile focal range from a wide 6mm to a telephoto 60mm, suitable for applications where the field of view needs adjustment without swapping lenses. It is designed specifically for cameras with a 1/3-inch image sensor format and features a standard CS mount for compatibility with a wide range of CCTV, industrial inspection, and specialised imaging equipment. The lens provides a corresponding angular field of view from 44 degrees down to 4.58 degrees as you zoom, allowing you to frame subjects from broad scenes to detailed close-ups. With a maximum aperture of f/1.6, it performs effectively in various lighting conditions, while its all-metal construction and compact dimensions make it a practical choice for fixed or compact system designs.

Features and Construction

Built for precision and durability, this lens incorporates key optical and mechanical specifications that define its performance and application scope. The following details cover its core build and practical fit.

Material and Build

The lens barrel and mount are constructed from aluminium alloy, providing a robust and lightweight housing that protects the internal glass elements. This metal construction helps maintain precise optical alignment and offers resistance to everyday handling. The manual focus and aperture rings are directly integrated into this barrel design, offering tactile control for precise adjustments.

Size and Practical Fit

With dimensions of 37mm in diameter, 68.7mm in length, and 34mm in profile height, this lens maintains a compact form factor. Its total weight is 118 grams, making it suitable for applications where size and weight are considerations, such as on portable devices or multi-camera arrays. The CS mount interface is a standard fitting for many industrial and security cameras, ensuring straightforward mounting and removal.

Uses and Placement

The lens's specifications make it applicable for both professional monitoring and technical imaging tasks. Its manual controls and varifocal range provide adaptability for different scenarios.

Event or Professional Use

In professional settings, this lens is well-suited for fixed security or observation installations where operators may need to digitally zoom into a specific area of a wide shot without losing optical clarity. The manual varifocal design allows the field of view to be set during installation and then left, or adjusted as needed for different events or monitoring focuses. Its f/1.6 aperture supports usable performance in the variable lighting conditions often found in venues, warehouses, or outdoor perimeters.

Everyday Home Use

For dedicated home security systems or hobbyist technical imaging projects using compatible 1/3-inch sensor cameras, this lens offers a cost-effective way to gain focal length flexibility. Users can set it for a wide overview of a garden or driveway, or adjust it to a longer focal length to monitor a specific entry point like a door or gate more closely, all with a single lens.

Benefits and Buying Value

The value of this lens lies in its specified optical performance, standard compatibility, and practical design, which together reduce the need for multiple specialised lenses.

Reuse and Low Maintenance

The durable aluminium construction and manual mechanical controls are designed for long-term use with minimal maintenance. The lens lacks complex electronics or moving parts that could require servicing, and its standard CS mount means it can be transferred between compatible cameras as needs evolve, protecting your investment.

Why Choose This Product

This lens is a practical choice for users who need a single lens solution covering a wide focal range for a 1/3-inch sensor camera. Its manual controls offer direct, repeatable adjustments, and its f/1.6 aperture provides a performance advantage in lower light compared to slower lenses. The combination of its metal build, compact size, and standard mount offers reliable performance in a straightforward package.
