Am considering purchasing either the Sony HVR Z7U or the Canon XH A1. I'm going to use them primarily for underwater work and need them to be broadcast qulaity HD as i have a number of projects coming that require HD qulity. I'm very intrested to know which of the 2 cameras perform better under low light conditions and the differences between the AF on both cameras. Also, the manual white balance capabilities and how they perform after they have been WB . . .
Any help and advice would be gratefully received . . .
