Inon M67 Lens Adapter Base for Canon Powershot G15 inside the Canon WP-DC48 Underwater Case. By using the mount base you can attach conversion wet lenses to further improve the performance of your camera. The INON UCL-165 M67 or other M67 macro lenses can be used. For the wide angle option the M52-M67 adapter is required to connect the UWL-S100 ZM80. This can further be widened using a dome port to achieve a very wide/semi fisheye effect.
