EDATEC 13MP 3.25mm M12 Lens for Raspberry Pi

Yes, this EDATEC 13MP M12 lens is compatible with Raspberry Pi camera modules that support interchangeable lenses and have an M12 mount interface, including models designed for high-resolution sensors. You must verify your specific camera board has a standard M12 thread. The 13MP resolution is well-matched for modules like the Raspberry Pi High Quality Camera or third-party 13MP sensors. Installation involves unscrewing any default lens and carefully threading this one on, followed by manual focus adjustment to achieve sharp images for your application's working distance.

The 3.25mm focal length provides a wide field of view, typically exceeding 90 degrees diagonally depending on the specific camera sensor size. This wide-angle perspective is excellent for applications like room monitoring, robotic navigation, or capturing large areas without needing to pan. It reduces the need for multiple cameras in some setups. For precise horizontal and vertical angle calculations, you need to consider the active sensor dimensions of your specific Raspberry Pi camera module, as the field of view is a function of both focal length and sensor size.

To install, first power down your Raspberry Pi. Carefully unscrew the existing lens from the camera module's M12 thread in a counter-clockwise direction. Then, thread the EDATEC 3.25mm lens onto the mount clockwise, avoiding cross-threading. Do not overtighten. To focus, point the camera at a detailed target at your desired working distance, display a live video feed on a monitor, and slowly rotate the lens barrel until the image is sharp. You may need to slightly loosen a locking screw if present. Secure the lens once focus is achieved. This process requires careful handling to avoid damaging the sensor.
