The next generation of WWL-1 is here! The WWL-1B features the same stunningly sharp optics as the WWL-1, but it now includes an integrated aluminum buoyancy collar to make it nearly neutral in water. The WWL-1 and now WWL-1B are still the highest quality wet-changeable underwater wide-angle conversion optics ever made, featuring unmatched contrast, overall sharpness, corner sharpness, and clarity. The design is truly full zoom through, allowing zoom to to be used as a tool for framing, and removable in water for close-up and macro shots.
