What is the difference (if any) between the 2.35:1 and 2.39:1 aspect ratio? I don't know much about cameras or film but I figured I would ask . I looked everywhere online and I couldn't get a straight answer. Some places say that 2.4:1, 2.35:1, and 2.39:1 are the same, but mathematically there is a difference (albeit negligible). Any info would be much appreciated. Thanks!
