WFL17 Wide Angle Wet Lens

Description

A phone's main camera sees a narrow slice of the reef underwater, because the water in front of a flat window magnifies the image and cuts the angle of view. The WFL17 is designed for smartphone cameras with sensors up to the 1/0.98-type format and a 23 mm main lens, and screws onto the 67 mm thread of a phone housing such as the WeeFine Smart Housing. At 0.58x it turns a 24 mm view of 84.1 degrees into about 142 degrees, and a 23 mm view into 150 degrees. On a reef it fits a whole coral head into the frame from close range, on a snorkel it captures a broad scene close below the surface, and on a wreck it records large structures without backing away. Five elements in five groups sit behind an optical-grade polycarbonate dome in a Type II anodised aluminium barrel. It weighs 390 g in air and 140 g in water and is rated to 80 m. It suits a smartphone shooter who wants a far wider view.
