Gizmodo has published a comparative review of four new action cams that have hit the market recently namely: The Drift Ghost, Sony Action Cam, Contour+2 and GoPro HERO3 Black. The testers found that the Ghost seemed somewhat unfinished and had a poor image quality, the Sony also did not deliver great footage, and seems to suffer from a poor build quality. The Contour was reliable, but lacked color accuracy. The HERO3 was, predictably, the leading product with only a limited battery life letting it down.
The testing was carried out with the cameras mounted on a surfboard, static shots were taken from a rooftop and then all three were strapped to a cyclists helmet while he pedaled around Brooklyn. The full test results are available on Gizmodo.
