Simmod ARRI PL to Canon RF Cine Pro Adapter

The Simmod ARRI PL to Canon RF-Mount Cine Pro Adapter is a precision-machined adapter designed to mount ARRI PL lenses onto Canon RF-mount cameras while maintaining proper registration distance, alignment, and mechanical stability.

Mount Interface

• Lens mount: ARRI PL
• Camera mount: Canon RF

The adapter installs between the lens and camera body, allowing PL-mounted cinema lenses to operate on RF-based 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 PL interface
• Fixed RF 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 PL to RF conversion
• Supports infinity focus
• Designed to preserve optical alignment between lens and sensor
• Compatible with vintage and modern lenses, including lenses with floating optical groups

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

Support System

A removable Arca-type support foot is included for additional lens support.

• Integrated mounting support for heavier lens setups
• Designed to reduce stress on the camera mount during operation

Dust Protection

A removable locking dust cover is included because standard RF 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 PL lenses and Canon RF camera systems
• Intended for cinema workflows involving support systems and follow focus accessories
• Shim adjustment may be required depending on camera and lens tolerances
