i am upgrading my filming camera and dont know what to get and need yalls help. I am looking at the sony handy cams, cannons, and maybe even panasonic. I am going HD for sure. i plan to get a shotgun mic to go with it to get the full effect of the sound also. I am willing to spend around $300-$500 just for the camera. What models of these cameras would yall recommend. I cant afford anything more then that. Any and all help is appreciated!!!
