Thanks for the great idea! I am just upgrading to the L & M Bluefin Pro for the Sony XR520 with SUnray 2000 lights, 110 Fathom lens, OLED screen. This will be my first system with the ability to manually white balance. I was thinking through the logistics of trying to hold the housing, hit the button on the side of the housing, and hold a slate in front of the lens. Thsi will fix the prob entirely!! Ordered a 3/4" setup tonight!
This reply might be too late, but I think you might consider the 1/2" setup for the L&M
