Lens Adapter Novoflex FUG/NIK — mount Nikon F lens to Fujifilm G (G-Mount) camera

Novoflex FUG/NIK is a mechanical lens adapter that enables mounting Nikon F-mount lenses on Fujifilm G-Mount (G) cameras. The adapter provides a solid metal-to-metal connection and maintains the optical alignment between lens and camera body without electronic contacts. Designed for manual focus and manual aperture control, it preserves the native characteristics of legacy Nikon glass while adapting it for use on modern Fujifilm G-series mirrorless bodies for both still photography and video.

Advantages

The adapter offers a rigid, precisely machined interface that minimizes play and ensures repeatable lens positioning. Because it contains no electronic circuitry, it does not alter the lens' optical path or introduce signal conversion, preserving the lens' original rendering, color and contrast. Its all-metal construction provides durability and stable mounting, while the compact profile keeps the adapted setup balanced and suitable for handheld use or gimbal mounting.

Suitable for

• Photographers who want to use manual-focus Nikon F lenses on Fujifilm G-mount bodies
• Videographers seeking the look of legacy lenses for cinematic footage
• Users who require a robust mechanical connection without electronic communication
• Adaptation of prime and zoom Nikon F lenses for creative optical effects

Key specifications

• Mount type: Nikon F (lens) to Fujifilm G (camera)
• Construction: precision-machined metal body for durability
• Optical interface: passive mechanical adapter — no electronic contacts or signal transmission
• Focus control: manual focus only (depends on lens mechanical focus ring)
• Aperture control: manual aperture operation using lens aperture ring or stop-down if lens lacks a ring
• Flange focal distance compensation: designed to maintain correct register for infinity focus
• Finish: corrosion-resistant coating on metal surfaces
• Weight and dimensions: compact, lightweight profile for maintained balance on camera

How to use

Attach the adapter to the rear of the Nikon F lens by aligning the mount indices and turning until it locks into place. Then align the adapter with the Fujifilm G-mount on the camera body and rotate until it engages securely. Set the lens to the desired aperture using its aperture ring; if the lens requires stop-down metering, use the camera’s exposure preview or live view to check exposure. Focus manually using the lens focus ring and use the camera’s focus assist tools (focus peaking or magnification) if available. Remove the adapter by reversing the installation steps.

Usage recommendations

Use with lenses that have full mechanical aperture control for the best shooting experience. When shooting video or handheld stills, check balance and consider support options if using large or heavy Nikon lenses. Be aware that autofocus and electronic communication are not supported; rely on manual focus tools and in-camera exposure aids for precise results.
