CineD [Review on movie capabilities] Sony A1 shows state-of-the-art consumer camera results in the lab test in all disciplines: rolling shutter, dynamic range, and latitude, using the internal codecs [... ] As long as these cameras use the current 12bit sensor read out architecture for video we cannot expect much more than these results.
