For close-focus wide angle work, Zen Underwater is turning conventional 'big dome' wisdom on its ear with a 100mm (4") dome port. As an added bonus, the DP-100 offers welcome relief to the luggage bloat of dive photo travel and the ever increasing expense associated with checking large heavy camera systems. The DP-100 allows the photographer to get in close where a large dome just won't go for stunning close focus wide angle images.
