These shots were taken by my wife Ginnie who is a member but never bothers to post. She has an E-620 in an Olympus housing and a 14/54 lens in a flat port. This rig allows both decent wide angle shots (28mm FX equivilent) and macro shots (.4-1 magnification). In my view this rig is an underconsidered option for photographers moving up from a point-and-shoot. Total cost of the rig (camera, housing, port and lens) is about $2500. Ginnie also has 2 INON Z-240 strobes that, with tray and arms, add about $2000 to the cost.
