Teradek has announced TOF.1, a lightweight infrared rangefinder for its RT Wireless Lens Control System. The TOF.1 constantly determines the exact distance between the plane of focus of a camera and the object to be filmed by infrared measurement and displays it, thus enabling a focus puller to focus precisely manually at any time.
In addition, TOF.1 can also be used as an autofocus system with the help of Teradek's FIZ system, purchased from RTMotion 2018 and renamed Teradek RT Wireless Lens Control System, which continuously tracks a motif and automatically adjusts the focus by means of a lens motor when movement occurs.
LED infrared beams measure the distance of objects within a 3-degree field of view of the TOF.1 proximity sensor, with a direct line of sight of up to 30.5 meters. The overall radius of the sensor's field of view narrows or widens as an object moves away from or away from the camera.
Included is a detachable laser sight, which can be used to precisely aim at objects in the image section on which to focus.
Both power supply and control are realized by a single control cable which is connected to the Teradek MDR.X receiver of the lens control system CTRL.1 or CTRL.3.
Teradek TOF.1 Display on SmallHD Monitor
The distance currently measured by the TOF.1 is then displayed on a connected CTRL.1 or CTRL.3 controller, the MDR.X as well as on connected SmallHD monitor with Pagebuilder OS4 via RT overlay in addition to the previously displayed information like follow focus information like lens focal length, aperture, zoom of the FIZ system. SmallHD's PageOS 4 software also allows for resizing and positioning of the overlay of distance information. This autofocus function can be activated by the wireless control with a simple on/off switch.
The Teradek TOF.1 is now available on the market at a price of around ,500 - the matching Teradek RT CTRL.3 Wireless Lens Control Deluxe Kit (with 3 motors) costs around ,500.
