well its time for a new camera, and i want to upgrade big time. now tell me the differnece between a DSLR- camera and a compact HD camera? ill be filming skiing, skiing, dirtbikes, and wake ski. i shoot from a tri-pod and dolly at times but mostly follow cams and free hand shooting. i just dont kno what to get and whats a good price for it. I want a dvx or Panasonic AG-HPX170 P2 HD Camcorder. i really truely dont kno where to begin with this so a lil direction would be nice.
