EDATEC 4MP 7.7mm M12 Lens for Raspberry Pi

This 4MP 7.7mm M12 lens is designed for 4MP camera sensors. The Raspberry Pi Camera Module 3 uses a 12MP sensor with a different optical format. For optimal performance, use this lens with specific 4MP Raspberry Pi-compatible camera boards that feature a standard M12 mount, such as certain Arducam or third-party 4MP modules. Always verify your camera board's sensor resolution and thread specification before purchase.

To install, screw the lens clockwise into the M12 threaded mount on your compatible camera board. For focusing, you may need to adjust the lens rotation while viewing a test image on a live feed. Loosen any locking screw slightly, rotate the lens to achieve sharp focus at your desired working distance, and then retighten the screw to secure it. Use a well-lit, high-contrast target for the most accurate focus adjustment. Handle the lens by its edges to avoid smudges.

The field of view depends on the camera sensor's size. On a standard 1/4-inch sensor commonly used with 4MP Raspberry Pi cameras, a 7.7mm lens provides a moderate field of view, approximately similar to a standard lens on a smartphone. It is not an ultra-wide-angle but offers a natural perspective suitable for general imaging, object recognition at medium range, and scene monitoring without significant distortion at the edges of the frame.
