Towards a Universal Standard
ARRI shares LPL specifications openly and free-of-charge across the industry in order to establish the LPL lens mount as the new standard interface between cameras and lenses.
ARRI LPL lens mounts are available for ALEXA LF, ALEXA Classic/XT/SXT, ALEXA Mini LF, ALEXA Mini, AMIRA, and ALEXA 65 cameras. In addition, third parties already offer LPL lens mounts for non-ARRI cameras, director's viewfinders, and lens testing tools, so ARRI Signature Primes and other LPL lenses can be universally used, allowing for maximum flexibility and return on investment.
The PL-to-LPL adapter, which attaches securely to the LPL lens mount without tools, offers backwards compatibility with all PL mount lenses. The PL mount was meant to work with 35 mm image-sizes, whereas the PL-to-LPL adapter enables compatibility with PL lenses on future cameras if respective image sizes are taken into account.
