Arri Alexa Mini LF

Arri Alexa Mini LF

700.00

Combining the compact size and low weight of the popular ALEXA Mini with the large-format ALEXA LF sensor, ALEXA Mini LF brings exciting new creative possibilities to ARRI’s large-format camera system.

Optimized for large-format lenses, the LPL lens mount fitted to ALEXA LF and ALEXA Mini LF cameras accepts ARRI Signature Primes, ARRI Rental DNA LF and 65 format optics, and third-party LPL lenses. The PL-to-LPL adapter, which attaches securely to the LPL lens mount without tools, offers backwards compatibility with all PL mount lenses, be they Super 35 or full frame. LDS-2 or /i lens metadata is accessible via the LPL mount, and LDS-1 or /i via the PL-to-LPL adapter. ARRI’s Frame Line and Lens Illumination Tool, available in the Learn & Help/Tools section of the ARRI website, illustrates how much of the large-format sensor is covered by a given lens.

Other manufacturers, such as Panavision and Vantage, offer proprietary lens mounts for the ALEXA LF and ALEXA Mini LF cameras, to support their own lens ranges. Cinematographers therefore have an almost unlimited lens choice when shooting with ARRI large-format cameras.

Product Highlights:

  • Three internal, motorized large-format FSND filters: ND 0.6, 1.2 and 1.8

  • New dedicated, regulated 12 V and 24 V accessory power outputs
