After reading the problems with the HD1 and HD1A, namely the low light sensitivity (they should have fixed this in the HD2) and the dreaded dark semicircle in the photo/video if you have an add-on lens (due to the interference of the lens with the built in flash), I was wondering if anyone can recommend to me an external flash or light. My main criteria would be its portability and good battery life and the battery is chargable, and, of course, the light can attach to the camcorder. I dunno if I need to buy additional brackets(?) to mount the light? Thanks for the info!
