I need some small cameras to mount on vehicles (for driver POV and for the driver himself), and am curious as to what you all are using. There are a number of inexpensive cameras (FlipHD, Contour) which seem to make great pictures in the right light, but when the angle and as a result, the light, shift, the auto-exposure mode kicks in, they get fooled by white sky (for example) into underexposing.
When I started researching this question, I realized that some of the tiny AVCHD cameras probably offer a lot more bang for the buck (manual exposure, manual focus, and even XLR inputs) than the "obvious" choices. They are a little bit bigger, but I'm not helmet-mounting. The biggest challenge is to find one with a wide-angle lens. I can hardly resist the option to glue a wide-angle auxiliary lens onto a Flip, though....
I usually just use my FX1 but there are many lipstick cameras and helmetcams to choose from.
You can get wide angle adapters for the fx1 and most liekly for whatever camera ya end up going with. I shoot while driving as part of a show I produce. It's first person pov is it's hook. I've never rented an extra camera for any part of it... just drivin' and shootin'
