I just upgraded cameras, so my baby has got to go. It an Olympus E-PL2 camera (red), 14-42 kit lens, and the PT-EP03 under water housing. This combination takes great photos, and is perfect for scuba divers wanting to get into underwater photography without spending thousands to house a bigger DSLR.
The neat thing about this Olympus housing is that you can use it as is for a number of other lenses, including the 12-50 and 9-18 zoom lenses; the 12mm, 25mm, 45mm primes; and the outstanding 60mm macro lens. You can add different ports and use even more lenses- the micro four thirds format is pretty handy for diving, and it's great for topside, too.
This package includes the camera, housing, lens, 2 batteries, charger, and two o-rings. It's used, but the housing was soaked in freshwater after every salt water dive, and has been well-maintained- it's never been flooded, and never exceeded 120ft (it's rated for 130ft). $500 for local to me (Oregon), or an extra $10 if I have to ship.
