Arducam 1/2.5″ M12 Mount 4mm Focal Length Low Distortion Camera Lens M2504ZH05S

The Arducam 1/2.5″ M12 Mount 4 mm Focal Length Low Distortion Camera Lens (M2504ZH05S) is a precision optical lens engineered for embedded camera applications, robotics, surveillance, machine vision, and DIY imaging systems. With an optical format suited to 1/2.5″ sensors and a 4 mm effective focal length (approximately 43 mm 35 mm equivalent), it strikes a balance between wide coverage and detail capture. The lens offers a wide diagonal field of view up to ~96° on compatible sensors and maintains very low distortion (~1%) to ensure images remain true and undistorted across the frame. Featuring an M12 thread mount for broad compatibility and a standard F/2.8 aperture for balanced light intake, this compact lens is ideal for Raspberry Pi camera modules and other embedded vision platforms needing enhanced optical performance. Note that the lens holder is not included and may need to be selected separately depending on your module setup.
