I have a Fathom Port/Lens that works with a Light & Motion Bluefin Housing for a Sony A1U, HC1 and others. The Fathom model number on the port is WP80-4-167. It is in pristine condition! This lens allows you to shoot wide angle and macro with full zoom through. This is an awesome lens. List is $1800, first $1000 takes it including shipping to the lower 48 states. Contact me for shipping elsewhere.
