If F-Map is disabled, when creating a new lens table on the LDT-R1, the lens brand,
lens name, lens type, focal length and serial number needs to be manually entered.
When a lens is changed on the camera, the new lens needs to be manually selected
on the LDT-R1.
Preston HU3 lens tables can be exchanged between other Preston HU3s by using the
Preston dongle and mobile app. Please visit the Preston website for more
information.
Adding a New Lens with using F-Map
Mount a new lens to the camera. On the Preston MDR press the calibrate button.
This will calibrate the LDT-R1 as well. Once calibration finishes, on the Preston HU3
create a new F-Map of the lens attached to the camera. If the lens has already been
F-Mapped, select it on the Preston HU3. In the LDT-R1 menu:
● Choose: Menu > Add Lens.
The LDT-R1 will display a message with the name of the lens. If the lens name
matches the lens mounted on the camera and the one loaded on the Preston HU3,
press 'ACCEPT' to proceed.
Lens details will auto-populate. Proceed to 'Creating a New Lens Table' chapter.
Adding a New Lens without using F-Map
