New Lens Mapping System for the LDT Ecosystem


London – April 2024

DCS is excited to announce a major update to the lens mapping workflow for our LDT (Lens Data Transmitter) ecosystem. Effective April 2024, all lens tabling will be done through the LDT-R2, streamlining the process across various camera systems.

The Old Method Explained

Previously, LDTs compatible with ALEXA cameras (LDT-A2 & LDT-M2) used ARRI’s built-in LDA lens tabling system. This required a computer for large bodies or an ARRI lens control handset for Minis/35 to build lens tables. On the other hand, LDTs used with Sony Venice, RED, and Panavision DXL cameras relied on the built-in lens tabling system in the LDT itself.

The New Unified Approach

With firmware 1.49, the LDT-R2 can now convert lens tables directly within the unit, making them compatible with ALEXA cameras. Here’s how it works:

  1. Build lens tables on the LDT-R2 by calibrating each lens from the lens control system and manually inputting lens engravings into the LDT-R2,
  2. All lenses are automatically saved to the MicroSD card in the DCS .xml format,
  3. For ALEXA cameras, select the “Convert Lens Files” option, creating a new folder with ALEXA-compatible files on the MicroSD.
  4. Transfer these files to an ALEXA-formatted USB stick and load them onto the cameras.
  5. Rig and connect the LDT-A2 and/or LDT-M2 units for the shoot.

Simplified Workflow

With this update, an ARRI Lens Control System is no longer required for mapping lenses. The LDT-R2 can map and convert all lenses, streamlining the process.

If additional lenses are needed during a shoot, rental customers will receive a free-of-charge LDT-R2 when renting only LDT-A2/LDT-M2 units. This ensures you always have a unit on hand to build new lens tables.
