Garmin's new Virb action camera enters a crowded market with good options at the top (GoPro Hero3 Black Edition) and bottom (Monoprice MHD) of the price range. It's a little late to the game, but it has enough features that you might consider it against the alternatives.
The Virb is a chunky 177g camera that's heavier than its competitors. It comes in regular and elite varieties, but only the latter really makes sense, because it comes loaded with GPS as well as Wi-Fi so you can control it remotely. Both cameras come with a built-in 1.4-inch display that uses the sun's light for their own radiance to conserve energy (smart!). The cameras are waterproof down to one metre for up to 30 minutes. Garmin says the products are larger than others because they promise industry-leading battery life: Three hours versus 2-2.5 hours on other action cameras.
As for its shooting specs, the Virb shoots the standard 1920x1080 footage at 30 fps. You'll have to scale down to 1280x720 to record slow-mo friendly 60fps footage. The cameras shoot 16-megapixel stills.
Here's a listing of available mounts: shoulder, head, wrist, bike (2), tripod and a fabric head strap. There's also an adaptor for use with mounts from other manufacturers.
The Virb will cost $US300 and the Virb Elite will cost $US400. At those prices, you can get a top GoPro, so the beefy Virb is going to have to deliver on image quality if anyone is going to pay attention to it. It's available in September, but there's no word as yet on what the deal will be in Australia.
