I'm selling my whole underwater photography gear. Unfortunately I have to do so because I have no time anymore.
I have an auction up on ebay (see here: http://www.ebay.com/itm/171531108443?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649)
Included is the Ikelite housing (all electronics have been changed for $350 by the manufacturing company about 10 months ago).
8-inch dome port, Ikelite DS125, Charger, ball arm, sync cable and additional parts. Please see ebay description for more details.
If you want to make me an offer before auction end please email me at: firstname.lastname@example.org
I do consider selling my Nikon D700 and the 20mm f2.8 lens as well since it's the only camera that fits in the housing.
I do NOT sell single parts. It's a set. If you are interested in the D700 and the lens you need to buy the housing or win the auction.
Otherwise I'm happy keeping the camera.
