The Neptune Convertible Art Lens System
The Neptune Convertible Art Lens System offers unlimited photographic possibilities. Attach one of the interchangeable front lenses to the lens base to shoot with a fixed focal length of 15mm, 35mm, 50mm or 80mm; and combine them with a wide range of f/stops and special aperture plates to achieve countless creative styles. This is just the beginning though – the Neptune System is made to expand.
