The 3D1 clip seems to be overexposed by the bright fluorescent light above the keyboard
I agree with that as well.
Listening to the sound difference, I would also say after several listens that the 3D1 appears to have a higher frequency response but it is not smooth and the appearance of the higher frequencies than the Sony is more that the 3D1 captures a peak response in the 1200-2Khz range giving it a more tinny quality. The Sony appears to be smoother and has smooth sound extending into the higher harmonics. I would liken it to comparing a cheap Radio Shack Microphone to a Sennheiser(Sony).
The bit rate difference doesn't seem to be as important than what appears to be the basic lens distortion in the 3D1. I'm sure if we had a third camcorder, the Panasonic Z10k in the mix with it's 3 chip design, it would shine equally as well over the Sony, but that is as higher level of product as the Sony is above the 3D1. We're really comparing Apples to Oranges here.
The bottom line in these comparisons, is whether the 3D1 meets your minimum standards for quick documentation of an event. Or, do you just get rid of it and keep the Sony always handy. This is the decision I made and so far, I find the 3D1 adequate to satisfy my quality standards. If I need serious planned production, the Sony TD10 I have will be used. My Bloggie 3D never quite met my needs and am happy to retire it, replacing with the 3D1.
