So the production company I used to work for has made the switch to 100% digital from their old Arri's.  They outfitted 7, 7D packages to film ski/snowboarding in the mountains of Wyoming, Alaska and beyond.
They needed a lens that wasn't really available to DSLR's so they made a pretty cool rig and are actually selling them if anyone is interested. Pretty cool read.
