A donut is either an alternative to this, or a safety precaution used always. Donuts come in all sizes to match the various size of lens front diameters. You may change donuts often with Panavision superspeeds, but only use one for a set of Cooke S4's. Regardless, your zoom will probably have its own. Hope that helps!
