FIZ Systems (Focus, Iris, Zoom) and How to Use Them

In this article, we take a look at the evolution and application of the FIZ system — including their unparalleled ability to control the camera remotely.

Over the last five years, it’s become standard to pull focus remotely on most feature film and television sets. By not needing to touch the camera, the focus puller doesn’t run the risk of interfering with the operator and eliminates the weight and power requirements of having a second focus monitor on the camera body. The focus puller can stand off to the side, out of the shot, and do the job via wireless transmission.

Since most cine lenses have not just one gear but three — one each for focus, iris, and zoom — it was only a matter of time before systems evolved that had three motors, allowing the focus puller to change any or all of these at the same time.
