Used highest settings for both: 1920x1080i, highest bit rate, auto focus, WB, exposure
Edited with Sony Vegas Pro 8
Only editing done is to render to 720 for Vimeo - sharpness was noticably reduced due to downscaling for both the HF100 and HDR-CX12
The HF100 is cousin to the HF10 and HF11. The CX12 is cousin to the SR11 and SR12.
