Key Features — ARRI 6-Lens Set
Six-Lens Prime Set: Includes 18mm, 29mm, 35mm, 47mm, 75mm, and 125mm focal lengths, providing a well-spaced progression from wide-angle to short telephoto for a full production kit.
Consistent T1.8 Aperture: Every lens in the set shares a maximum aperture of T1.8, allowing cinematographers to cut between focal lengths without resetting exposure.
LPL Mount: ARRI's Large Positive Lock mount supports large-format cinema sensors and is compatible with cameras such as the ARRI ALEXA LF and ALEXA Mini LF.
Large-Format Coverage: Each lens covers a large-format image circle beyond full-frame, making the set suitable for ARRI's large-format digital cinema systems.
Manual Focus Design: Smooth, precisely dampened focus barrels are built for use with follow-focus systems and lens control motors standard in professional cinema workflows.
Unified Lens Mechanics: All six lenses share consistent front diameter, focus and iris gear positions, and rotation direction, minimizing rig adjustments when swapping focal lengths on set.

Description — ARRI 6-Lens Set
The ARRI Signature Prime 6-Lens Set is a coordinated collection of six manual focus cinema prime lenses built for the LPL mount and covering a full-frame lens format. The set spans 18mm to 125mm across six individual focal lengths — 18mm, 29mm, 35mm, 47mm, 75mm, and 125mm — providing a well-distributed range for narrative and commercial productions. Every lens in the set shares a maximum aperture of T1.8, giving cinematographers consistent light transmission and a unified exposure baseline throughout the set.
There is no autofocus and no image stabilization included, which aligns with the professional cinema production environment where manual lens control via external motors and follow-focus rigs is standard. Each lens weighs 4.4 lb individually. The set is classified as a Cine lens type targeting the Cinema / Video camera system category, and is positioned for large-format digital cinema production workflows.
