Next Generation LDS-2 Lens Data System

The ARRI Signature Prime range is first to incorporate ARRI’s next-generation LDS-2 Lens Data System, with high data rates and absolute encoders for fast initializing. LDS-2 extends the possibilities of lens data and is being licensed to other lens and camera manufacturers.

Compatibility of Signature lenses

ARRI has shared LPL specifications openly and free-of-charge across the industry, establishing the LPL lens mount as a standard interface between cameras and lenses. ARRI LPL lens mounts are available for ALEXA 65, ALEXA 35, ALEXA LF, ALEXA Mini LF, ALEXA Classic/XT/SXT, ALEXA Mini and AMIRA cameras. In addition, third parties offer LPL lens mounts for cameras, director's viewfinders, and lens testing tools, so ARRI Signatures and other LPL lenses can be universally used.

LPL Mounts for ARRI and 3rd Party Cameras

ARRI Signature Lenses are compatible with nearly all digital cinema cameras on the market.
