The Sea & Sea M52 Wide-Angle Conversion Lens For Olympus PT Waterproof Cases is a wide-angle lens with an M52 screw mount designed for certain Olympus PT-series waterproof cases. It enables you to get closer to your subject while still fitting everything in-frame, thus minimizing distortion and improving image clarity and quality. The lens is constructed from a corrosion-resistant aluminum alloy with an anodized finish. It changes the camera's focal length from 28mm to 18mm (35mm film equivalent), provides 0.65x magnification, and offers 85° and 106.5° angles of view underwater and on land, respectively. A true amphibian of a lens, it is usable both on land and underwater, and can be attached and removed beneath the surface, as well. It boasts a depth rating of 200' (60 m).
When used on land, slight vignetting (dimming) may occur in the 4 corners of the image. Zoom in slightly to telephoto in order to eliminate this effect. Additionally, a shadow may appear in the image if the built-in flash is used while the lens is mounted. It is highly recommended that an external strobe be used to improve lighting quality.
The lens is compatible with the Olympus PT-045, PT-047, PT-048, and PT-051 waterproof cases.
