The Venus Optics Laowa 24mm 2X Macro Probe Lens is an amazing macro lens that provides a 2:1 max magnification with a compelling wide angle ‘Bug Eye’ perspective. It features a wide angle design means much greater depth of field at close distances. It has very distinct and unique long and slender barrel with an LED ring mounted on the tip of the lens. The front barrel of the lens is also waterproof. Since Laowa designed the end of the 24mm macro probe lens to be waterproof, the Nauticam port for the Laowa lens leaves the original front element of the lens ourside the port opening. It is a particularly innovative and elegant design and truly opens the flood-gates to a wonderful creative new style of imaging. The Nauticam N120 Port Adaptor is designed to be used for the Laowa 24mm f/14 2x Macro Probe Lens with either cinema housings or dslr housings. The lens also comes in two Focus/Iris control variations, the Standard and Cine-mod versions. The Cine-mod version features de-clicked aperture adjustments as well as cinema-styled focus to allow for easier follow focus.
