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.
It is the most refined Alpha-series interchangeable lens camera yet. Its combination of speed and resolution for both stills and video set it apart in a crowded field of excellent options, though that combination is also responsible for the price it commands. [...] Most any professional photographer will be able to use the a1 for most anything they'd think to shoot.
