Sony HDR-SR8E with 800 GB harddrive gives video with duration 13.5 hour in a best quailty. SR8 compressing video into AVCHD standard with resolution 1440x1080 pixel. The SR8E has a fair level of high-end features. The built-in lens cover opens automatically when the camera is turned on. The accessory shoe is of course Sony's propriety version, so third-party accessories won't fit. This is a shame, as minijacks are built in for microphone and headphones. But the accessory shoe also supports Sony's 5.1 surround microphone, the ECM-HQP1, assuming you can find one for sale. If you can't, the built-in microphone has three channels - left, right and rear - which it uses to mix the surround signal it records to Dolby Digital 5.1.
