Purchased from H.Preston, via Amazon - some time to arrive, maybe because it had to be sourced from Sony in Europe. At first switch on, error message displayed: "HD movie area in internal memory is full. Cannot record HD movies". H.Preston had been very efficient at registering the camera with Sony PrimeSupport, since it's considered a Pro product. Sony engineers thought that the unit could be faulty and arranged for a replacement, which arrived very quickly.
Same error message! They then suggested using 'Reset' which had no effect. In the Operating Guide, there was a clue that there might be a need for formatting the internal memory as there is mention of writing unintelligible data to the internal recording media before transferring the unit to another owner, so I wondered if this was the factory-supplied status? Applied 'format internal memory', which seemed to work (hooray!), and a test recording was successfully made.
There was no specific mention in the Operating Guide that this should be necessary and it would have been helpful if this was flagged up when beginning to set up the camera. Surprised that Sony support engineers didn't latch on to it, either!
The camera is superb, brilliant Hi-Def images and a wealth of facilities. Proper XLR audio inputs with 48v phantom power for external microphones or mixer to be connected. Records either to internal memory or SD card, or simultaneously if required. Also still-shot capable and auto or manual control of all functions. Bring the HD in your home!
