The PrimeCircle system consist of an adapter ring and a control system with one or two unit, wired or wireless.

The adapter goes directly onto the FZ mount of the Sony F3, F5 and F55 and allows the use of Sony E-mount lenses. The ring maintains the electrical contacts that powers the lens motorization, including the aperture.

The adapter is connected to a small unit with an LCD screen that offers precise control over the lens aperture while displaying the exact iris value. The same unit also controls some other functions like the ability to change the aperture over a specific duration.

It’s possible to use a second wireless unit that communicates with the first one and allows for the same controls.
