thing is, no one can touch the c300 c500 for handling. they are lovely, compact, all in one units that smash out their broadcast legit signal into cf cards. own one of these and you can hire it out week in, week out when not using it yourself. it'll pay for itself. After being in close contact with the c300 a few times, briefly using one I fell in love. sony can reel out loads of higher specs than the c500 but id rather have a basic 50mbit broadcast ready, in camera 1080p from a lovely small package than have to cart around a 'wheel around' flightcase full of all the modules and hard disks for the f55.
