I haven't used it everywhere I need to yet (maybe since it's summer), but from 100ks to 4k, the runtime is anywhere between 30 and 40 minutes, air temperature permitting. Even after an hour and a half of filming at full power conservation, a 4K 100x camera doesn't get too hot. Why do they only provide $4000 instead of $2700? If you want to know how to get your photos and videos from your camera to your computer quickly and easily, MTP was, at 10 it' or download via phone and then on to your computer, satisfied with the camera 4 out of 5, especially for 32022, let's say. Two weeks have passed, but filming has not stopped.
