Since most people will buy the CF module, like they did for the R1, and it sits on the left... where the REC button should be, like on every other cinema camera in existence..... You could put a REC button on that module.... sorry if that made too much sense.
I guess I should make my own camera system instead of telling you obvious things like that, oh wait I don't have billions of dollars to do that so I'll just suggest it to someone who does and has a forum for that purpose.
I don't need 5 buttons in the wrong places. I just 2 buttons in the correct places. 1 on the right, 1 on the left, and if you want to get crazy 1 on the back too.
If you believe those are the "correct" places, then I would think this camera is not for you.
