I notice that you're asking this after you already purchased them. Hope you're not getting buyer's remorse. Here is a promising test that Ryan E. Walters did with the Zeiss ZF set, it showed their quality to be quite impressive and up there with zeiss cinema lenses:
Dan, there's something very special about a lens with high MTF values. Some call it more contrast, some call it organic...but there's no question that there's a very noticeable difference. Other than our Nikon 17-35 f2.8d zoom lens, we haven't used anything but the Zeiss lenses here since we got a hold of a set for our own use.
You're going to see some ground-breaking footage in a week or so that will make you feel very, very good about your Zeiss lenses
