I like the Go-Pro, I also like the Sony MC1P, different tools for different jobs. The Sony MC1P has a built in screen on the end of an umbilical cable, so you can position the camera where you want it while viewing the pictures on the monitor. The Go-Pro can have a postage stamp size display clipped on to it’s back for framing, but this is next to useless when the camera is mounted in a tight spot where you can view it’s rear end.
Enter the Replay XD1080. This new POV camera (shipping at the end of the month) is small and compact, but the best bit IMHO is that it has an integrated HDMI output. This make plugging in a monitor, or recording to an external device like a NanoFlash nice and easy and makes this unit sound particularly versatile. In addition it will take an external microphone making it well suited to use in race or rally cars.
Looks like this will be a strong contender in the POV camera market. Only a few years ago minicams were few and far between and very expensive. Now we have lots of choice at great prices.
