If you've been lusting after a 180 degree magnifying viewfinder for your DSLR housing, here's one at a bargain price. This finder is bright and sharp, can be adjusted for your eyesight, and with an adapter (not included) can fit Ikelite, Aquatica, Sea and Sea, and Nexus housings. (Adapter isn't necessary for Nauticam housings.)
The cost new is $1150. I'm selling this gently used one for $575.
If you also need a Nauticam housing for the Nikon D7000 see my post elsewhere on this board and perhaps we can work out a deal for both.
