Prototype by cmotion seen at Cine Gear: focus and iris motors for Leica Summilux-C Primes from Band Pro. The motor assembly attaches directly to the lens with a bracket, providing a way to control focus and iris without having to use lens rods.  This helps keep things light, tidy and compact for handheld, remote, Steadicam and 3D rigs.

The motor assembly will probably provide encoding for lens metadata. The prototype attached with two hex screws or thumbscrews for quick mounting when changing lenses. Of course, having purchased a complete set of Leica Summilux-C lenses, presumably price is a minor detail, and for a few dollars more you can mount each lens with its own motor set. Saving a few minutes per lens change adds up during the day, and the extra cost might be quickly recovered in additional rental or eternal gratitude from the producers.

For those of us who have to ask, a set of 8 Leica Summilux-C Primes will set you back a mere $178,000. Operators are standing by at Band Pro.
