I only had a short time to run around Newtown yesterday and shoot some street stuff. I tried to pick things with lots of detail and get a sense of how the sensor renders color. Check them out however there is no way you can get an idea of how big and versatile these files are until you actually work with them.
I think using them is initially going to be a little slow until I update, at this point the PC is handling them better than the Mac but that is possibly because of the extra RAM packed into the PC.
The color is spot on accurate and gives you so many options for grading plus the massive files allow for some aggressive cropping if needed.
Next big test will be the night shoot and long exposures. I did notice that it actually goes down to 64 ISO which will be handy for blurring movement.
