Arducam C-Mount Lens for 12MP IMX477 HQ Camera
Best for Raspberry Pi HQ Camera users seeking a ready-to-go 16mm option. This lens provides manual focus and adjustable aperture to fine-tune depth of field on the 12MP IMX477 sensor. It aims to reduce shading and dark corners, delivering a straightforward plug-and-play experience with compatible modules. The 44.6°(H) × 33.6°(V) field of view makes it suitable for general close-to-mid-range scenes and product photography. Choose this if you want a cost-effective, tested lens that “just works” with minimal setup.
Who it’s for: hobbyists and makers using the Raspberry Pi HQ Camera who want consistent results without extensive calibration. Limitation: manual controls may slow rapid shooting compared to auto-focus zoom lenses.
HTENG VISHI 16mm 2/3″ Fixed Focal Lens
Best for industrial machine vision with a 2/3″ image size and low distortion. This 16mm fixed focal lens is designed for stable imaging in automated environments, offering predictable performance under controlled lighting. The lens is a practical choice for setups requiring reliable, repeatable frames without complex adjustments. Choose this if you operate in assembly lines or quality-control imaging where consistency matters. Caution: compatibility with your sensor size must be verified prior to purchase.
HTENG VISHI 16mm 1/1.8″ Fixed Focus Lens
Best for higher-resolution applications needing a larger image format. This 16mm lens uses a 1/1.8″ size and fixed focus to minimize focus drift in industrial environments. It includes features like low distortion (<1% as noted) and good overall sharpness for precise imaging. Best for dedicated imaging stations or fixed installations where frequent recalibration is impractical. Limitation: fixed focus means closer-than-expected subject distances may require repositioning.
Arducam CS-Mount Lens Kit (6–25mm)
Best for versatile testing and a broad field of view. The CS-mount kit includes five focal lengths (6mm, 8mm, 12mm, 16mm, 25mm) so you can quickly compare FoV and perspective with your Raspberry Pi HQ Camera. It’s a curated selection chosen for predictable performance, avoiding guesswork. Best for projects requiring quick experimentation with different views. Caution: for true macro or macro-like work, dedicated macro lenses are preferred.
Xenocam CCTV 16mm Fixed Lens
Best for straightforward CCTV or entry-level camera setups requiring a fixed 16mm focal length. This lens provides a 21° angle of view and a fixed F2.0 aperture, suitable for standard surveillance or hobby projects. It is a simple, reliable choice when a fixed, non-adjustable lens aligns with project needs. Limitation: fixed aperture and focal length reduce flexibility in dynamic lighting or distance conditions.
Buying Guide
- : Verify sensor size compatibility (1/3″, 1/2.3″, 2/3″, or 1/1.8″) and mount type (C-mount vs CS-mount) for your camera module.
- : A 16mm lens generally offers a similar angle of view, but the exact FoV depends on the sensor size and lens design. Choose based on desired scene coverage.
- : Lenses with wider apertures (e.g., F1.6) perform better in low light and deliver shallower depth of field. Fixed-aperture lenses are predictable but less flexible in changing lighting.
- : Manual focus and aperture provide control for precise scenes, while automatic features speed up general shooting. Consider how frequently you’ll adjust focus or exposure.
- : A flexible CS-mount kit is useful for testing multiple focal lengths, while a dedicated 16mm fixed lens is simpler and often more robust for a single use case.
- : Industrial-focused lenses emphasize low distortion and stable performance; consumer or hobby lenses prioritize cost and ease of use.
- : Ensure correct back focus alignment, verify compatibility with the camera’s sensor size, and check if vibration or lighting conditions affect performance.
Frequently Asked Questions
- What’s the difference between CS-mount and C-mount? CS-mount lenses are designed for compact cameras and require shorter back focus. C-mount lenses are longer and compatible with a wider range of cameras, including many Raspberry Pi and industrial cameras.
- Is a fixed 16mm lens better for video than a zoom? Fixed focal length lenses offer consistent performance and often sharper results at their designed distance, while zooms provide flexible framing across scenes.
- Can I use these lenses with Raspberry Pi HQ Camera? Yes, several 16mm c-mount options are compatible, especially those designed for IMX477-based HQ Cameras or with CS-mount adapters.
- Do I need to worry about distortion? Some industrial lenses advertise low distortion (<1%). Distortion matters for architectural or measurement-focused work; for general photography, it’s less critical.
- What should I consider for low-light use? Lenses with larger maximum apertures (e.g., F1.6 or faster) perform better in dim lighting, and sensor compatibility remains essential.
- How important is back focus adjustment? Back focus helps ensure the image is sharp at the intended distance. Some lenses include adjustment rings; others require mounting alignment.
