That's interesting but it makes me wonder why we'd ever shoot interlaced if all the end use nowadays is progressive. > Note that there are settings for 'wide, medium, narrow' and these relate > to field of view.

Knowing nothing about Gopro cameras, this is also interesting to me. Only because I see so much footage that annoys me because of a fisheye effect. Do the narrower views eliminate the distortion or just reduce it? FWIW a lot of other companies are coming out with action cameras now, eg Shimano and Garmin. I'm not sure if Contour is still around. It's good to see some more companies getting involved. I wouldn't mind playing with one of these things but when I think a bit more seriously I just don't know what I'd want to achieve with it.
