GoPro is introducing three new models of its tiny, rugged sports cameras today, including two high-end models and an introductory model that offers a cheaper way to start buying into its camera line. The two two high-end models are the Hero4 Black and the Hero4 Silver. The Black model’s headline feature is its ability to capture 4K video at 30fps, twice the frame rate that its predecessor was capable of recording. It can also do 1080p at 120fps, which GoPro says is fast enough to “virtually eliminate” the unsightly rolling-shutter effect that comes with shooting digital video. It’ll go on sale for $ 499.
