Totally renewed optical design effectively suppresses flare/ghost even in backlit condition to provide sharp and high quality image. The UWL-95 C24 is designed to support a camera of large 1.0 type sensor with bright master lens. Using the UWL-95 C24 can dramatically reduce minimum focusing distance enabling to get subject on the lens in focus both on land and underwater.
The lens mount is versatile M67 or M52 mount. The M67 version has two types either of Type1 or Type2 having different threaded thickness to bring out optimal performance of different combined master lens. Optional M67 Type1 Screw Ring for UWL-95 C24 or M67 Type2 Screw Ring for UWL-95 C24 is available to purchase making it easy to modify from M52 Mount to M67 Mount or convert original M67 type to the other type(*2).
