Underwater stills are Eric Cheng's passion and -- from what we gather -- livelihood, but the award-winning editor of Wetpixel is presently experimenting with faster and deeper photography. Discovering German shop Digi-Dat, he wound up with this custom BS Kinetics DuoDive case, which turned his pair of Sony CX550V camcorders into a totally badass underwater 3D camera that will no doubt make manta rays pop out of his screen. If you'd like to follow in his fins, €2,900 (about $3,700) will buy you a similar pair of synchronized stereoscopic goggles, but note that it takes the shop four to five weeks to integrate the watertight LCD and all the LANC-based controls.
