Metabones Leica M to Fuji G-Mount GFX Adapter

SKU CH-GC5W-DK9AM

Precision adapter mounts Leica M lenses on Fujifilm G-mount GFX cameras with manual aperture control and chromium-plated brass construction

  • Precise fit preserves optical integrity with Leica M lenses
  • Maintains original focal length for consistent framing on GFX
  • Manual aperture control enables creative exposure flexibility
  • Brass and aluminum alloy construction ensures durable mounting
  • Matte-black interior minimises internal reflections for maximum image quality

Leica M to Fuji G-Mount GFX Adapter

The Metabones adapter connects Leica M-mount lenses to Fujifilm G-mount GFX medium-format cameras. It is built for photographers who want to use their existing manual-focus M glass on the larger G-format sensor while retaining the lens's native focal length and manual aperture control.

Precision brass construction with chromium coating

The mount surfaces are machined from brass and coated with chromium on both the camera and lens sides for smooth, repeatable mounting. A leaf-spring mechanism on the lens side secures a tight fit that reduces wear and prevents focus-shift or alignment errors. Internal matte-black treatment suppresses reflections to protect contrast and colour fidelity.

Manual aperture control via Smart Adapter

The adapter incorporates Metabones Smart Adapter electronic interfacing, enabling true electronic control of the Leica M lens aperture directly from the Fujifilm GFX camera body. This allows aperture adjustments without mechanical linkage on the lens, providing consistent exposure control for adapted manual lenses.

Questions about this item

How is the adapter attached to the GFX body and which step avoids a loose mount?

Align the red index on the adapter flange with the red dot on the G-mount throat, insert straight, then rotate clockwise until the body lock clicks; forcing the turn before the click seats the brass bayonet off-centre and introduces play.

What part may need replacement after heavy lens changes?

The brass lens-bayonet leaf spring that locks Leica M lenses can lose tension over time; Metabones sells a replacement spring kit that a user can swap with a small hex key.

What limit appears first during long exposures or video?

The all-metal barrel conducts sensor heat to the lens mount, so the camera's thermal throttle activates sooner than with a native G-mount lens, capping recording time.
