IA is an image extension associated with some of the older models of Sinar cameras. Sinar is a Swiss brand with a prestigious name dating back to the 1940s, manufacturing large and medium sized cameras which tend to be popular among professional photographers. The latest models of Sinar cameras use DNG (Digital Negative) as a default format for shooting in RAW mode, but many of the older models use the IA format.
