The Cine-Mod Pro usually consists of a 95mm thread-on front ring, a 95mm front cap, a large focus gear and an aperture de-click. With ZE lenses, however, there is no de-click due to the fact that the iris is controlled electronically through the camera. Some users prefer the electronic communication between the lens and the camera. Those who prefer a manual aperture go with the ZF.2 versions and have them converted to EF mount.
