Some quick comments regarding sensors and log profiles.
We do offer two forms of raw output; one via Thunderbolt and one via SDI. Like the Sony F5/55 series cameras, our raw output is linear because this is the most "untouched" signal we can provide from the sensor.
Log profiles are most often applicable when your sensor A/D exceeds your encoding ability. For example, you have a 14-bit A/D and you want to save an 8-bit file (a common case with many of the cameras in the market today). Log acts as a form of compression allowing you to get the 14-bit "mapped" as well as possible into an 8-bit container. Now consider that the AJA CION uses a 12-bit A/D, performs 12-bit processing, and then stores this in a 12-bit container (Apple ProRes 4444). In this method, you maintain the same specificity throughout. If you encode 10-bit with the camera, you are not making a huge sacrifice because the processing has been performed at 12-bit prior to the 10-bit encode.
The proof is always in how well an image holds up when "exercised" in post. Starting with a 12-bit or 10-bit image is always a good starting point.
I hope this is helpful,

This is hugely helpful. Thanks, Jon. I need to read up a bit more on this stuff.
