DZOFilm Marlin 1.4x Expander (ARRI PL to L-Mount)

Overview

The DZOFilm Marlin 1.4x Expander (ARRI PL to L-Mount) is a professional optical lens mount adapter designed to expand the image circle of Super 35 cinema lenses for use on full-frame L-Mount cameras. By magnifying the projected image by 1.4x, the adapter helps retain the original Super 35 angle of view while allowing lenses to cover larger full-frame sensors.

Built with premium optical elements and precision-engineered mechanical components, the Marlin 1.4x Expander delivers exceptional image quality, reliable lens mounting, and fast back focus adjustment without the need for shims. Its robust construction makes it ideal for professional productions, rental environments, and demanding cinematography workflows.

Core Features

• Expands the image circle of Super 35 lenses to cover full-frame L-Mount camera sensors.
• Provides 1.4x optical magnification while maintaining excellent image quality and resolution.
• Limits light loss to approximately one stop for efficient low-light performance.
• Features integrated back focus adjustment for quick calibration without shims.
• Uses high refractive-index optical elements and large-diameter aspherical lenses.
• Internal flocking minimizes reflections and helps control unwanted optical artifacts.
• Precision CNC-machined stainless steel mounts ensure long-term durability and mounting accuracy.

Retain Super 35 Coverage

The Marlin 1.4x Expander allows cinematographers to continue using existing ARRI PL-mount Super 35 lenses on modern full-frame L-Mount cameras while preserving the intended field of view and visual characteristics of their lenses.

Professional Optical Design

• High-quality SR optical elements help maintain sharpness and image integrity.
• Large-diameter aspherical elements support excellent optical performance across the frame.
• Designed to preserve resolution while expanding lens coverage.

Fast Back Focus Calibration

The built-in back focus adjustment mechanism simplifies lens setup and eliminates the need for traditional shim adjustments. This allows operators and rental technicians to quickly fine-tune focus performance when changing lenses or camera bodies.

Built for Production Use

Constructed from aluminum and stainless steel, the Marlin 1.4x Expander is engineered for reliability in professional production environments. The CNC-machined mounts provide secure lens attachment while internal flocking helps suppress reflections and maintain image quality.
