If the waterproofing and full HD video capture of Kodak's Playsport interests you, but you can't live without an optical zoom, check out Sanyo's newest Dual Camera Xacti, the VPC-CA102YL. (Oh Sanyo, you come up with such clever, memorable names.) Waterproof to depths of 10 feet, its pistol-grip design accommodates a 5x zoom lens that the candy-bar-style minicamcorders simply can't.
Sanyo says it records at "full HD," but depending on your definition of the term, that may not be true. It does capture video at a resolution of 1,920x1,080 pixels, but it's interlaced, not progressive. However, it is at 60 frames per second, which should make for some pretty smooth video. Plus, and perhaps unsurprisingly given Panasonic's ownership of Sanyo, you can store to SDXC cards, which currently max out at 64GB, allowing up to 480 minutes of video. Of course, those cards currently cost a little more than $200, so it's more of a future-proofing thing.
Like all of the company's Dual Camera Xacti models, this one takes still photos just as easily as it captures video; in this case, at the unnecessary resolution of 14 megapixels. Also, Sanyo says it has a 38mm-equivalent wide-angle lens, but that isn't really wide at all. Other noteworthy features include a flip-out rotating 2.7-inch LCD, a Mini-HDMI port, and support for Eye-Fi SD cards for wireless transfers directly from the device.
It'll be out in August at an MSRP of $349.99. (Seems a bit pricey to me.)
