That is sooooo cool. I just tried it and it seems to work as describe. What I'm not clear on is if, for example, I set the ISO @ 200 with the Fn control, and the Coercive Custom Control is set to 1600, if the exposure would be made at any established ISO rating (400, 800, 1600), or if it will default to 1600. I keep getting 1600 as the ISO, but maybe different light is needed.
