EDATEC 8MP 1.67mm Ultra Wide Angle Lens for M12 Mount

This lens is compatible with any camera module featuring a standard M12 (S-mount) thread and an 8MP or lower resolution sensor. It is commonly used with Raspberry Pi Camera Modules (with an M12 adapter), OpenMV Cam boards, and various industrial USB or CSI-interface cameras designed for machine vision. Ensure your camera's sensor size and flange distance are suitable for wide-angle optics to avoid vignetting.

To install, align the lens threads with the M12 mount on your camera module and rotate clockwise until snug. Do not overtighten, as this can damage the threads or the sensor alignment. For cameras without a native M12 mount, you will need a compatible M12 lens holder or C/CS to M12 adapter. Always handle the lens by its edges to avoid smudging the optical glass, which can degrade image quality.

The exact diagonal field of view depends on your camera's sensor size. On a standard 1/4-inch sensor, a 1.67mm focal length typically provides an ultra-wide diagonal FOV exceeding 120 degrees, capturing a very broad scene. For precise calculation, use the lens focal length and your sensor's active imaging area dimensions in an online FOV calculator to determine horizontal, vertical, and diagonal angles for your specific application.

Yes, but an adapter is required. The Raspberry Pi High Quality Camera uses a C-mount. You will need a C-mount to M12 step-down ring adapter to attach this 1.67mm lens. Note that using an ultra-wide-angle lens on a large sensor may cause severe vignetting (dark corners). It is best suited for cameras with smaller sensors, like the standard Raspberry Pi Camera Module V2, when used with an appropriate M12 lens holder.

This is a fixed-focus (prime) lens, meaning its focus is set at the factory for a specific hyperfocal distance, providing acceptable sharpness from a near point to infinity. It is not designed to be manually refocused. For optimal results, ensure your subject is within the lens's depth of field. If sharpness adjustment is needed, some M12 lenses allow focus adjustment by rotating the entire lens barrel, but this model is typically pre-set and sealed.
