does anyone currently make a nikon mount zoom with aperture control on the barrel?

I am interetsed in using a depth of field (DOF) adapter from Red Rock Micro, the M3, with a video camera and it seems as though none of these manufacturers make a zoom with aperature control on the barrel: Sigma, Tamaron, Tokina, Rokinon. The adapter does not have a ring that mates up to the control on some nikon lenses so...
