Simmod ARRI LPL to Leica L-Mount Cine Pro Adapter

The Simmod ARRI LPL to Leica L-Mount Cine Pro Adapter is a precision-machined adapter designed to mount ARRI LPL lenses onto Leica L-mount camera systems while maintaining proper registration distance, alignment, and mechanical stability.

Mount Interface

• Lens mount: ARRI LPL
• Camera mount: Leica L-Mount

The adapter installs between the lens and camera body, allowing LPL-mounted cinema lenses to operate on Leica, Panasonic, Sigma, and other L-mount camera systems without modification to the lens or camera.

Mechanical Design

The adapter is designed around a rigid mechanical structure intended for cinema lens support and alignment.

• Positive-locking LPL interface
• Fixed L-mount connection
• Reduced rotational play and mount movement
• Designed for use with heavier cinema lenses and support systems

The mount geometry is engineered to maintain alignment under operational load.

Construction

• Solid brass construction
• Chrome-plated mount surfaces
• Satin exterior finish
• Internal felt flocking to minimize reflections and stray light

The adapter is CNC machined to maintain dimensional consistency and fit accuracy.

Mechanical Performance

• Maintains proper registration distance for LPL to L-Mount conversion
• Supports infinity focus
• Designed to preserve optical alignment between lens and sensor
• Compatible with vintage and modern lenses utilizing floating optical elements

A shim set is included for flange depth adjustment and calibration.

Support System

An optional support collar is available for additional lens support.

• 360-degree rotating support design
• Integrated:
  • 1/4"-20 thread
  • 3/8"-16 thread

The support system is designed to reduce stress on the camera mount when using larger cinema lenses.

Dust Protection

A removable locking dust cover is included because standard L-mount body caps cannot attach directly when the adapter remains mounted on the camera.

This allows:

• The adapter to remain installed on the camera body
• Sensor protection during storage or transport
• Faster lens changes within configured setups

System Behavior

• Fully mechanical adapter
• No electronic communication or metadata transfer
• Manual lens operation only
• Does not alter optical characteristics of the lens

Notes

• Designed specifically for ARRI LPL lenses and Leica L-mount camera systems
• Intended for cinema workflows involving support systems and follow focus accessories
• Shim adjustment may be required depending on camera and lens tolerances
