belt focus

Just for interest, this sort of lens lends itself to automated or motorised focus when used with a robofocus motor cotrol and a rubber belt, as seen in the pic. This allows focus to be reached quickly. In this case I have a large CCD camera attached. I didn't get any useful results with this rig though - everytime I attempted it cloud was in the way and I've since moved on to other gear.
