I beta tested the Letus Extreme 35mm adapter before its release. Here is one of the tests I did using 3x250w Lowel ProLites and a 1k Spiderlite softbox as a key (you can see that light reflected in the vase and there are also hotspots throughout this piece...BAD STEVEN!!) :)
My daughter is my lovely assistant and it was shot on a Canon XHA1 (with the Letus, obviously).
It's amazing how many lights it takes to make a scene look like it wasn't lit.
