DEMA 2008: Aquatica
Aquatica has always listened to its users, and have moved from a casting their housings to milling housings from a solid block of aluminum, which results in a lighter, prettier housing. They had on display brand-new underwater housings for the Nikon D700 and D3, and for the Canon 1D/1Ds Mk III. Older, cast housings (like the Nikon D300 housing) were on display as well.
I picked up the D700 housing, which had good ergonomics, down to angled buttons on the left-hand side of the LCD display on the back for easier access while gripping the handles.
