Lens mount adapter KiwiFotos Close Focus II for Leica M to Fujifilm X

KiwiFotos Close Focus II for Leica M to Fujifilm X is a mechanical lens mount adapter that lets photographers attach Leica M‑mount rangefinder lenses to Fujifilm X‑mount mirrorless cameras. The adapter aligns the optical axis and secures lenses to APS‑C X‑system bodies while adding close‑focusing capability to adapted optics. It is designed for stills and video use where maintaining manual aperture and focus control is required.

Advantages

The adapter preserves mechanical coupling for manual focusing and aperture control, enabling the use of a wide range of Leica M lenses on Fujifilm X bodies without electronic communication. It provides a short flange focal distance conversion while adding a built‑in close‑focus mechanism that reduces minimum focusing distance compared with a simple passive adapter. The construction is metal for durability and stable mounting, and the adapter maintains the original lens optical character and manual handling.

Suitable for

• Photographers who own Leica M‑mount rangefinder lenses and use Fujifilm X‑series mirrorless cameras
• Portrait, street, documentary and product photography where manual focus and aperture control are acceptable or preferred
• Videographers using manual vintage or specialty lenses on Fujifilm X cameras

When it may not be suitable

The adapter does not provide electronic communication between lens and camera, so autofocus, EXIF lens data, and in‑camera aperture control are not available. Users who require full electronic integration or autofocus functionality should consider native X‑mount lenses. Close‑focus performance is improved versus a basic passive adapter but will still depend on the optical design of the attached Leica M lens; extremely close macro work may remain limited.

Key specifications

• Mount conversion: Leica M mount to Fujifilm X mount
• Compatibility: Manual Leica M lenses to APS‑C Fujifilm X bodies
• Functionality: Mechanical coupling with close‑focus mechanism, no electronic contacts
• Construction: Metal exterior and mounting flange for stable attachment
• Supported use: Still photography and video with manual focus and aperture

How to use

Attach the adapter to the Fujifilm X camera by aligning the adapter's mounting mark with the camera mount and turning until it locks. Mount the Leica M lens onto the adapter following the lens' alignment marks and secure it in place. Focus and set aperture manually on the lens; use the camera's focus assist tools (such as magnification or focus peaking) to achieve accurate focus. To extend the close‑focus capability, follow any specific mechanical adjustments or locking steps described by KiwiFotos for the Close Focus II adapter.

What to consider before purchase

• Adapted lenses remain fully manual: no autofocus, no electronic aperture control, no EXIF lens data
• Close‑focus improvement depends on the attached lens design and may vary between lenses
• Ensure physical compatibility with your specific Leica M lens (lens rear element clearance) and Fujifilm camera model
• Metal construction adds weight and changes balance compared with native lenses

Usage recommendations

Use focus peaking and magnified live view on your Fujifilm camera to achieve precise focus with manual Leica M lenses. For portraits and product shots, stop down the lens slightly to increase depth of field and compensate for the closer focusing distance. Store the adapter in a protective pouch when not in use to avoid dust and scratches on mounts.
