The RE has a 146 degree wide-angle lens (so you don’t have to worry too much about framing the scene), slow-mo capture, a 16 megapixel CMOS sensor and full HD (1080p).
It’s waterproof and has clever stabilisation tech so you don’t get video vibration later. Plus, if you want a bit more protection, there’s a Protection Pack which adds a waterproof-enhancing cap, protective lens cap, and neck and wrist lanyards.
