The Hero 7 Silver also has a lower-end 10-megapixel sensor. Its 4K footage doesn’t look as sharp to detailed as the Black models, and that’s down to the quality and size of the sensor, not just its resolution. You also miss out on RAW photo capture, the Black series’ super-effective HyperSmooth stabilisation (it does have electronic stabilisation, though) and 60fps 4K shooting.
GoPro is leading the charge toward consumer-created virtual reality (VR) environments, and their first VR-ready cameras make it happen with what they’ve dubbed “spherical capture,” which is pretty accurate, given the 360° field of view they record. VR is still a nascent technology, but it’s definitely the future. If you’re an early adopter, you’ll want to pick up a GoPro with spherical capture.
