I know, Brian, you warned and advised me before – but would i listen?!
I advise everyone who uses the Sony EX-1 camera in combination with FCP to leave the picture profile Blacklevel setting to 0 (zero) and adjust the blacklevel in FCP using a levels filter (i use Joe’s Levels filter: http://www.joesfilters.com/). This helps to reduce the noise in the darker areas of the picture, specially when using the cine gamma 3 or 4. Cine gamma 4 is the worst by the way.
I have updated my article on the EX1/3 picture profile: click here for the updated article
