Simmod Signature Series Front Cine Ring

Leica R 19mm f/2.8 Version II · 80mm Outer Diameter

Purpose-built with absolute specificity, this Signature Series Front Cine Ring is engineered exclusively for the Leica R 19mm f/2.8 Version II. No compromises, no universal fitments, and no guesswork. Just a precise mechanical solution designed around the exact geometry of this lens.

Designed for a Single Lens, Done Right

The Leica R 19mm f/2.8 Version II is known for its distinct rendering and optical character, but like most still lenses, it was never designed for modern cine workflows.

This ring converts the front of the lens into a true 80mm cine-standard outer diameter, allowing seamless compatibility with matte boxes and front-mounted accessories. The result is a clean, consistent interface that integrates effortlessly into professional setups.

Precision Machined Construction

Each ring is CNC machined from solid aluminum, delivering durability, accuracy, and a refined finish. The outer surface features a precision-cut knurled texture, providing confident grip when handling the lens or mounting accessories in fast-paced environments.

This is functional knurling, not cosmetic. It is designed for control under real shooting conditions.

Threaded, Lens-Specific Fit

Unlike generic step-up solutions, this ring is engineered specifically for the Leica R 19mm Version II.

• The internal threading is matched precisely to the front of this lens

• The ring installs securely and seats flush, maintaining proper alignment

• Once mounted, it expands the lens front to a uniform 80mm diameter

This creates a stable, centered platform for matte boxes and accessories without play or misalignment.

Why It Matters

Wide-angle lenses like the 19mm often present challenges when integrating into cine setups. Inconsistent front diameters can slow down lens changes and introduce unnecessary adjustments.

With this dedicated cine ring:

• The lens becomes part of a standardized front system

• Matte box positioning remains consistent

• Setup time is reduced, especially during lens swaps

• Handling improves with a solid, machined interface

The Simmod Approach

At Simmod, precision is not an afterthought. It is the starting point.

By designing this ring specifically for the Leica R 19mm f/2.8 Version II, the result is a component that feels native to the lens, not adapted to it. It preserves the integrity of the glass while elevating its usability on set.
