SIMMOUNT LEICA R to LPL CONVERSION MOUNT

Not all lenses are built for cinema. But the right mount can change everything.

This is not an adapter.
It is a conversion.

The Simmod SimMount Leica R to LPL Conversion Mount is engineered to transform classic Leica R glass into a true large-format cinema tool, bringing it into the world of modern digital cinema cameras that demand precision, rigidity, and reliability.

From Still to Cinema, Properly

Leica R lenses are revered for their optical character, but their original mount limits their use in high-end production environments.

The SimMount system replaces that limitation with a solid LPL mount interface, allowing Leica R lenses to integrate directly with modern cinema cameras designed around large-format sensors and professional locking mounts.

Precision-Engineered Mounting System

Each SimMount is machined to exact tolerances, ensuring a secure, play-free connection between lens and camera. The result is a mount that maintains accurate flange distance and reliable infinity focus, critical for professional imaging workflows.

• Positive locking LPL interface for maximum stability

• Eliminates flex, play, or misalignment under load

• Designed for consistent performance across demanding production environments

A lens is only as stable as its mount. This is built to hold up under real use.

Built for Modern Cinema Cameras

The LPL standard, developed by ARRI, was designed for large-format sensors, improved data communication, and more robust mechanical support.

By converting Leica R lenses to LPL, the SimMount:

• Unlocks compatibility with modern cinema systems

• Provides a stronger, more secure mounting platform

• Aligns vintage optics with contemporary production standards

Designed for Integration, Not Adaptation

Simmod’s approach is rooted in full-system thinking. This mount is part of a larger philosophy of transforming still lenses into cohesive cinema tools.

When paired with other Simmod modifications such as:

• Standardized front diameters

• Cine focus gears

• Declicked apertures

The result is a lens that behaves like it was built for cinema from the start.

Why It Matters

Adapters solve compatibility.
Conversions solve performance.

With the SimMount Leica R to LPL Conversion:

• Your lenses become native to your camera ecosystem

• Stability improves across handheld, rigged, and motor-driven setups

• Focus accuracy and repeatability are preserved

• Your investment in vintage glass becomes future-proof

The Simmod Approach

At Simmod, the goal has never been to simply make things fit.

It is to make them work better.The SimMount system reflects that philosophy. Clean, precise, and built for cinematographers who demand more from their tools than just compatibility.
