Lens Mapping and Lens Data Overlay

Updated on

CTRL.1 and CTRL.3 both feature built-in lens mapping, which allows users to auto-calibrate lenses to pre-marked focus rings with the touch of a button. Lens Mapping is a standard feature on the CTRL.3. For CTRL.1, Lens Mapping is included when you purchase the CTRL.1 Lens Mapping Package, or available for purchase as a separate upgrade. After purchasing the Lens Mapping Package, use the following steps to activate this feature.


  1. Press the MENU button, then use the τ button to navigate to the ADV (Advanced) menu. Press the SET button to access the menu.
  2. Navigate to the LICENSES menu. Press SET to display the UID number. 
  3. To generate a license key, visit activate.teradek.com and enter the controller’s UID, upgrade code, and your email address.
  4. On the same screen displaying the UID number, select YES to enter the license key. After entering the license key, you can now map the lens to the controller.


  1. Navigate to LENS>LENSMAP>CREATE
  2. Select the lens brand, then create a name to identify the lens map. 
  3. Select Yes to map a prime lens, then enter the lens’ fixed focal length (e.g. 35mm, 85mm). Select No if mapping a zoom lens, then create a focal length (zoom) table (e.g. 24-70mm, 70-200mm). 
  4. After setting the focal length, you will be prompted to create an Iris table. Ensure a motor is attached to the corresponding ring, and the motor and controller are set to the same class (Focus, Iris, Zoom). 
  5. Move the controller knob so that the motor adjusts the lens ring to the minimum stop. 
  6. Using the Up and Down buttons on the controller, enter the corresponding mark, then select OK. NOTE: Entering every lens mark is not required, but it is recommended in order for the Lens Map to be more accurate
  7. Press the MENU button, then select TABLE DONE
  8. You will then be prompted to create an iris or focus distance table, depending on the type of lens. Select YES, then repeat steps 5 through 7 for each motor you want to map. 
  9. Attach a lens ring to the controller’s knob. 
  10. Navigate to LENS>LENSRING>SELECT and select the corresponding lens ring size. 


SmallHD monitors include a Lens Data Overlay feature that displays your controller’s lens map position. Before activating the Lens Data Overlay feature, you will need the following:

  • Lens Mapping License - If you have a CTRL.1, you must purchase a Lens Mapping License. If you have a CTRL.3, the license is already included.
  • SmallHD/Teradek RT Interface Cable - Be sure you purchase the appropriate cable for your monitor.


  1. Update your CTRL.3/CTRL.1 controller and SmallHD monitor to the latest firmware.
