Sea & Sea 16mm SWL-16 super wide conversion lens for Nikonos 

Condition: Excellent condition. Lens has very clean front and rear glass surfaces, no dust or fog inside. 15mm viewfinder has few minor scratches on the rear surface (barely visible for naked eye). Will not influence the outcome. 
Description: The lens screws onto a 35mm even while diving. Lens can be put into BCD pocket, and when the opportunity to take a wide angle shot comes, just screw it right on and you are ready!!! This lens expands field of view from 46 to 91 degrees and reduces minimum focusing distance from three to one foot (30cm). The conversion lens is screwed in clockwise until secure. Set the focus of 35mm lens at infinity. The aperture should be between f/5.6 - f/22. Check yellow sticker on the lens for depth of field. 

The viewfinder has big optics making it easier to use while wearing a mask. Can be used with 35, 20 and 15 mm lenses.
