Arducam 8-50mm CS-Mount Zoom Lens
A Better Option: Adapt the CS-Mount of the Raspberry Pi High Quality Camera to a compact varifocal lens, with a C-CS adapter included. The lens offers 8-50mm adjustable focal length, plus a manual focus and aperture ring for precise control at different distances. Longest focal length of 50mm supports better telephoto reach for distant subjects. Best for users needing flexible focal range without changing lenses.
Best for: Raspberry Pi HQ Camera users who want a single lens covering wide to telephoto ranges, and hobbyists needing straightforward manual control.
Caution: Manual controls require careful adjustment to avoid focus hunting at extreme ends of the range.
Xenocam CCTV 5-50mm CS Lens
This lens is designed for 1/3″ CCD cameras with a CS mount and provides a practical 5-50mm focal range. It’s suitable as a replacement part for CCTV security systems and offers solid versatility for observing both nearby and distant scenes. The design supports straightforward manual adjustment with stable focus control.
Best for: CCTV setups requiring a general-purpose zoom with easy swap-in replacement parts.
Caution: It may lack advanced autofocus features found in higher-end lenses, relying on manual adjustment for focus and iris.
Zowietek 5-50mm CS Mount Zoom Lens
Versatile Zoom Lens: The Zowietek 5-50mm offers a low-distortion design intended for IMX477 and other compatible sensors. It supports manual focus and iris adjustments for precise control and performs well with Raspberry Pi HQ Camera setups and industrial telescopes. The 5-50mm range lets you frame subjects from broad scenes to tight crops.
Best for: Projects needing low distortion and precise manual control across a broad zoom range.
Caution: Listed compatibility includes several IMX formats; verify your sensor model before purchasing.
Hopcd 5-100mm CS-Mount Zoom Lens
Aperture Can Be Adjusted: The Hopcd lens provides manual adjustment for focal length across a broad 5-100mm range. It’s suitable for security cameras and situations requiring flexible framing across a wide field of view. The lens is designed to be compatible with common CS-mount cameras and offers practical zoom control.
Best for: Security and surveillance projects needing an extensive zoom range in a single lens.
Caution: Wide-range zooms can introduce distortion at the extremes; calibrate carefully for critical imaging tasks.
Arducam 4-12mm Varifocal CS-Mount Lens
A Better Option: This lens pairs with the Raspberry Pi HQ Camera via CS to CS adapters for a compact varifocal solution. The 4-12mm range covers close-in to mid-range subjects, with manual focus and iris control for precise exposure and depth of field. Field of view specifications show the adaptable nature across typical Pi camera setups.
Best for: Users wanting a small, flexible lens for desk setups or tight spaces with Raspberry Pi HQ Camera.
Caution: Lower end of the zoom range (4mm) may provide a narrower depth of field, requiring careful focus.
Buying Guide
What should I look for in a CS-mount zoom lens?
Key factors include focal length range, compatibility with your sensor (IMX, IMX477, 1/3″, etc.), manual focus and iris controls, and whether an adapter is included. Lenses with a wider zoom range offer flexibility but may introduce optical compromises at the extremes. Check distortion characteristics and field of view to match your subject distance and framing needs.
How does focal length range affect my project?
Shorter focal lengths (e.g., 4-12mm) provide wider fields of view and are good for close-range scenes. Middle ranges (5-50mm) balance field of view and magnification for general surveillance. Longer ranges (50mm+) suit distant subjects and telephoto requirements, but require stable setup to prevent hand shake or vibration.
Is manual control necessary for CCTV vs. Pi projects?
Manual focus and iris allow precise exposure and depth of field control, which is valuable in variable lighting or scenes with changing distances. For fixed setups or networked cameras with autofocus, you might prioritize ease of use, but manual lenses give predictable results in controlled environments.
Are adapters included with these kits?
Many kits include a CS to C-CS adapter or similar, but always verify what is included. An adapter is essential when pairing CS-mount lenses with C-mount sensors like some Raspberry Pi HQ configurations.
What are common limitations to expect?
Common limitations include potential distortion at extreme focal lengths, vignetting in wide angles, and the need for precise manual adjustments. Some lenses may not offer auto-iris control, requiring exposure compensation in changing lighting.
How to choose between five tested options?
For pure versatility across a broad range, consider lenses with 5-50mm or 5-100mm ranges. If you operate in compact spaces or need a lightweight option, a 4-12mm vari-focal lens is ideal. For longer distance subjects, prioritize higher focal lengths near 50mm. Always confirm compatibility with your camera module and sensor type.
