Vivitar’s forthcoming waterproof camera has pretty weak specs (why is the SD card limited to 1 GB?) and a deisgn aesthetic a bit reminiscent of the late KBGear’s JamCam for kids, but a cheap waterproof camera may be just the thing to address one of the last refuges of disposable cameras — the casual underwater photographer on vacation. We’ll see if the image quality is up to it. At $233, it’s not there yet, but at $99, many consumers might just take the plunge, so to speak. That price would also put it below many underwater casings for more popular offerings.
