Check out the first image (above left). That image definitely depicts this as a true "Extreme Sports" camera in my book. LOL. In the last month, there's more people talking about a fairly new Crocolis HD Sports Camera. In full 1080p mode, it has quite an almost normal 140 degree FOV (field of view) which is quite nice if you want something a bit different than the super wide fisheye look. I'm not sure what's going on in the beginning of this video (below), but jump on in at about 0:37 seconds, and you'll see some very clear and sharp underwater footage from this camera (no flat lens adapter required).
The HD Sports action camera has a 1.5" TFT LCD screen, rechargeable Li-Ion battery, built in microphone, claims a whopping 16 megapixel (still photo), video resolutions and frame rates in 1080p @30fps/25fps, [email protected]/30fps/25fps, and [email protected]/120fps, a 4x Zoom. Behind a rear door you'll find a mini HDMI port out, 3.5mm Microphone input, USB 2.0. The camera is waterproof in it's own housing. In the same bundle package are necessary cables, and adapters for a variety of sports mounting solutions.

Now Crocolis is doing an excellent job with marketing and brand recognition, but there's other names this camera falls under. If you can locate this under it's most basic name, you'll find it at a much cheaper price. You can find some of these HD video cameras on auction following the link (click here)
