Chris, we shall agree to disagree.
I honestly don't think it's too much to expect a camera's AWB to behave in a stable, consistent manner when used in bright sunlight while panning...consumer cam or not. Most cams I've used in that manner maintain a perfectly stable AWB in exactly those conditions. My Panny 700 never exhibited that behavior, yet two different Sonys (560 &700) did. Another owner reports the same thing and trust me, there will be more.
Both the CX700 and 560 behaved exactly the same way, so I have no reason to believe I got 'unlucky'. I've noticed for many many years that some camera lines will show this type of behavior and, invariably, the worst offenders in my experience have been Sony.
I feel strongly that when we all give the manufacturer's a 'pass' by assuming 'well, it's a consumer camcorder, what can you expect', we give them license to make more crap.
Anyone that's used a number of camcorders over the years knows very well that a consumer camcorder can be made with a stable AWB. Sure, under many conditions they may drift, but NOT in bright sunlight under a cloudless sky.
Likewise, we know that a consumer camcorder can be made without the injection of a 'beep' embedded within the audio. Panasonic had this same issue in a very UNconsumer $15,000 camcorder.
Nope, if we accept this crap then we fully deserve the crap we get. There are reasonable and unreasonable expectations. Stable AWB under non-demanding conditions, audio without recurring beeps, proper auto focusing across the field of view are among what I consider to be 'reasonable' expectations. Some may disagree.
