Arri Signature 65-300 LF. Accompanying and matching ARRI Signature Primes, the four new Signature Zoom lenses render the most natural and beautiful images ever seen from a cine zoom. Designed for any large-format or Super 35 camera, they are uniformly fast at T2.8 and offer an unrivalled focal length range. Significant extension of the Signature lens family, with the same timeless look as Signature Primes. ARRI Signature lenses cover a focal length range of 12 mm to 510 mm, which is the largest in the industry. Arri Signature 65-300 LF are equipped with the LPL (Large Positive Locking) lens mount. A wider diameter and shorter flange focal depth allow LPL lenses to be small and lightweight, with a fast T-stop and pleasing bokeh—a combination of features that would not be possible with the old PL lens mount. 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 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.
