The bike footage was all shot on a Sena 10C helmet mounted communicator. Camera, bluetooth and intercom all in one. Had it about 3 yrs now, and has hardly missed a beat.What did you use to record the videos? Totally agree that Sony makes great cameras; my understanding is many of them are great in low-light situations, as yours appears to be. I have a bulkier Sony camera (NEX-5, one of their mirror-less ones) which I love, but would want something more compact like the RX-100 for bike touring.
