Lens Mount Adapter Pixco FUJIFILM X (X-mount) to Nikon F (Ai/AiS/AF) — Pixco SB3027

Mechanical lens mount adapter that enables the use of Nikon F manual-focus lenses (Ai/AiS) and legacy AF-design lenses on Fujifilm X-mount mirrorless cameras. The adapter maintains correct flange focal distance for accurate infinity focus and does not provide electronic contacts, so aperture control and focusing remain manual. It is suitable for photographers and videographers who want to use vintage Nikon optics or specialist F-mount lenses on modern Fujifilm X bodies while preserving mechanical control over aperture and focus.

Advantages

This Pixco adapter offers precise mechanical alignment to preserve infinity focus and optical performance of adapted lenses. Its fully mechanical construction ensures a simple, durable connection without electronic dependencies, reducing potential compatibility issues with different lens generations. The adapter is compact and lightweight, adding minimal bulk to the camera-lens combination while providing a secure, solid mount for manual-focus operation.

Suitable for

• Photographers using vintage Nikon Ai/AiS manual-focus lenses on Fujifilm X cameras
• Cinematographers and videographers who need manual aperture and focus control
• Users adapting older AF-design Nikon lenses without electronic aperture control
• Enthusiasts experimenting with unique lens characteristics like bokeh and color rendering

Key specifications

• Mount conversion: from Fujifilm X (camera) to Nikon F (lens)
• Supported lens types: Nikon F manual-focus Ai/AiS lenses and older AF-design F-mount lenses
• Construction: mechanical, no electronic contacts or communication
• Function: preserves correct flange focal distance for infinity focus
• Control: manual aperture and manual focus only
• Form factor: compact and lightweight metal and/or alloy construction for durability

How to use

Attach the adapter to the Fujifilm X-mount camera body by aligning the adapter's index mark with the camera's mount mark and turning until it locks in place. Mount the Nikon F lens onto the adapter by aligning the lens's mounting index and rotating until secure. Since the adapter lacks electronic contacts, set aperture and focus manually on the lens. Verify focus at various distances, including infinity, and adjust diopter on the camera viewfinder if needed for precise manual focusing.

Usage recommendations

Use live view or focus magnification for accurate manual focus, especially with short depth of field lenses. Metering and focus assistance functions available in the camera can typically be used, but automatic aperture control and EXIF lens data will not be transmitted. Handle the adapter and lenses with care to avoid stressing the mount; store without attached lens when transporting for extended periods.
