Camera adapter is an integral piece of the 300Studio and P2Studio camcorder studio systems. Mounting to the back of a compatible P2 or DVCPRO HD camcorder, the unit is then attached via optional studio cables to the system's base station, allowing transmission of HD digital images, return images, tally signals, mic signals and genlock signals over distances of up to 100 meters (328ft). Lightweight and compact, the AG-CA300GPJ boosts mobility and allows the use of various professional batteries (with optional battery plate). This adapter is compatible with AG-HPX300 series, AG-HPX500 series, AJ-HPX3700, AJ-HPX2700, AJ-HPX3000, AJ-HPX2000/2100, AJ-HDX400 and AJ-HDX900 cameras.
