Description
The VIM-MX4K action camera sunglasses put a 4K camera in a pair of UV400 sunglasses you would wear anyway, so your point of view gets recorded without a helmet mount, a chest rig or a hand on a camera.
4K Ultra HD at 30fps in H.265, 24 megapixel stills on a button press while the video keeps running, a 65 degree lens that frames roughly what you are looking at, and 32GB of internal memory so there is no card to lose. The TR90 frame takes interchangeable TAC lenses. Battery is the tradeoff to plan around: about 30 minutes of continuous 4K from the 500mAh cell.
