Sanyo last week announced the DMX-CA100 for the Japanese market, the world’s first waterproof full HD camcorder “for consumer use with optical zoom lenses” (Kodak has released a simpler model just recently). And now we can (courtesy of DigInfonews Tokyo) give you a video that shows the device in action.

The camera boasts an IPX8 waterproof rating so that it’s safe to use it underwater (up to 3m deep) for a full hour. It’s marketed by Sanyo as a “dual camera”, meaning you can use it to shoot full HD movies as well as to make 14MP pictures.

Buyers will get an 1/2.33 inch CMOS sensor, 5x optical zoom and Sanyo’s proprietary “Double Range Zoom” function, which allows users to instantly switch between “Wide Mode” (40 mm to 240 mm) and “Tele Mode” (80 mm to 480 mm) with the push of a button (see graphic below).

The camera also features a 2.7-inch LCD, a USB 2.0 port, an SDXC port, and a mini HDMI interface. It’s also compatible to Eye-Fi, and comes with a digital image stabilizer and a “Face Chaser” function for videos.

Sanyo will start selling the DMX-CA100 in Japan at the end of this month in black, yellow, and pink (price: $440). International sales plans haven’t been announced yet.
