You can see that all the time in tv sitcoms or documentary style filmmaking where the camera quickly puches in and crash zooms but still stays in focus. It is important to mention that CATTA ZOOM cine lenses are parfocal. Means that your stays in focus throughout the entire zoom range of the lens. When your lenses are parfocal, all you have to do is to set your focus on your subject either fully zoomed in or fully zoomed out. And that's it you pull perfect focus every time throughout the entire zoom range of the lens.

When you change lens mounts, it may requires a lot of time and patience. Also when people do not have tools when you're out in the field or out on set. But DZO changes all of that simply unlock twist and the mount comes right off.
