Steve Weiss and Jens Bogehegn show how to use the Zacuto Z-Stop to stop focus drift when using Depth of Field Adaptors.

The Z-Stop locks onto the focus ring of any camera, preventing any accidental bumps that throw a DOF adaptor’s ground glass out of focus. The Z-Stop is made out of carbon fiber and industrial strength grip material, it also attaches simply and easily to any 15mm rod system. The Z-Stop keeps your camera system looking professional without the need to resort to tape or other methods to secure your focus. Made for cinematographers who utilize DOF adaptors, the Z-Stop is an invaluable tool in any DP’s arsenal.
