Professional Camcorders with 1/3 or 2/3 chips often work adequately with no camera rig.
However, their monitor placement and, shorter than an ENG camera form factor, mean a camera rig can be an appropriate choice. Partiularly if you need to add accessories for your shoot, a lavaliere receiver is often critical for sound and an external monitor or EVF can be required when filming in sunlight.
Cameras such as the Sony PMW EX1 need an external recorder to meet BBC 50 mb/s standards – this needs to be attached somehow, a power source may be needed for longer shifts.
We would suggest our T30 rig for use with an an EVF and lavaliere combination.
