ZEISS Ultra Prime LDS 50mm T1.9
Summary
ARRI LDS Ultra Prime lenses were the first to be kitted out with ARRI’s revolutionary Lens Data System (LDS). The LDS Ultra Prime series consists of ARRI Ultra Prime optical elements transplanted into specially designed housings that allow each lens to communicate with the camera electronically, easing tasks on set and providing valuable metadata for postproduction.

Known Issues:
1. ARRI and Sony didn't reach an agreement on LDS data so Sony cameras do not read LDS data so if anyone complains that their LDS lens is not working on a Sony camera specifically, it is because of this.
