the only thing that may be completely alien is the follow-focus. everything else is just a support for the camera. everything is designed around cinema industry-standard 15mm rods... adjust scale and size by turning those little blue knobs and sliding things around on the rods.
with the follow-focus, you simply attach the appropriate gear ring to your lens (based on diameter), slide the follow focus so that the little gear on the follow focus lines up with lens gear, turn the knob, and you have a dramatically more comfortable way to manually focus.
i've owned a lot of stuff by them in the past, but sold most of it off when the hdslr revolution happened (they were one of the earliest companies experimenting with shallow DOF adapters for small-sensor video cameras). i do have a couple of parts left, including their follow-focus.
