The Watec M5018-MP 2/3" C Mount 50mm f/1.8 Manual Iris Lens by Computar is a perfect match for a Watec high performance camera. It incorporates an advanced optics system to ensure excellent corner-to-corner sharpness and superb light conductivity. Its iris and focus can be manually adjusted to achieve a sharp and properly exposed image. As with a Watec camera, it also features an ultra compact design which adds minimally to the camera's overall length.
