Introduction

This manual provides detailed instructions for the proper use and maintenance of your Fringer NF-FX II Lens Mount Adapter. This adapter allows you to mount Nikon D/G/E series lenses, as well as compatible third-party auto lenses, onto Fujifilm X-series cameras, enabling electronic aperture control, autofocus, and other advanced functions.

Product Overview and Features

The Fringer NF-FX II is designed to bridge the gap between Nikon F-mount lenses and Fujifilm X-mount camera bodies, offering advanced electronic communication and robust construction.

Key Features:

• Electronic Aperture Control: Full automatic aperture control is supported for Nikon D/G/E lenses and most major third-party auto lenses. This includes both mechanical and electromagnetic aperture mechanisms.
• Autofocus Capability: Autofocus is available with Nikon AF-S and AF-P lenses, as well as other major third-party auto lenses.
• Lateral Chromatic Aberration (LaCA) Correction: The adapter features a built-in database for LaCA parameters, automatically correcting color fringes at high contrast edges directly in-camera. This function is supported for tested and optimized lenses.
• Phase Detection Autofocus (PDAF) Support: All phase detection focus points are supported for fast and accurate autofocus in both still and movie modes. Face/eye detection autofocus is also supported on X-Trans II, III, IV, & V cameras with optimized lenses.
• Image Stabilizer Support: The adapter supports lens-based VR/OS/VC functions and camera body-based IBIS (In-Body Image Stabilization). Refer to the user manual for specific limitations.
• Weather Sealing: Designed with weather sealing to protect against dust and moisture when used with compatible weather-sealed cameras and lenses.

Operating Instructions

Electronic Aperture Control:

Once a compatible Nikon D/G/E lens or third-party auto lens is mounted, the camera will automatically detect the lens and allow for electronic aperture control through the camera body's dials and menus. The aperture value will be displayed on the camera's screen and in the viewfinder.

Autofocus Operation:

The adapter supports autofocus with Nikon AF-S and AF-P lenses, as well as other compatible third-party auto lenses. Ensure your camera's autofocus mode is set appropriately (e.g., AF-S, AF-C). AF performance may vary depending on lighting conditions and specific lens models.

Face/Eye Detection Autofocus:

For Fujifilm X-Trans II, III, IV, and V cameras, face and eye detection autofocus is supported with optimized lenses. This feature enhances portrait and subject tracking photography.

Lateral Chromatic Aberration (LaCA) Correction:

The adapter automatically applies LaCA correction for supported lenses. This correction is performed in-camera, resulting in images with reduced color fringing. Note that this feature is only active for lenses that have been tested and optimized by Fringer.

Image Stabilization:

The adapter supports both lens-based image stabilization (VR/OS/VC) and camera body-based image stabilization (IBIS). The stabilization function is controlled via the camera's menu. Consult your camera and lens manuals for specific settings and limitations.

Maintenance

• Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the adapter. For the electronic contacts, use a clean, dry cotton swab. Avoid using harsh chemicals or abrasive materials.
• Storage: When not in use, store the adapter in a dry, dust-free environment. Attach front and rear caps to protect the mounts and internal components.
• Handling: Always handle the adapter by its body, avoiding direct contact with the electronic contacts or optical elements (if any).

Troubleshooting

• Lens Not Detected / No Electronic Communication:
  • Ensure the adapter and lens are securely mounted and clicked into place.
  • Clean the electronic contacts on both the adapter and the lens with a dry cloth.
  • Restart the camera.
  • Check if the lens is compatible with the adapter. Refer to the compatibility lists.
• Autofocus Issues:
  • Autofocus performance can vary with different lenses and lighting conditions.
  • Ensure the lens's AF/MF switch (if present) is set to AF.
  • Update the adapter's firmware to the latest version.
  • Test with different compatible lenses to isolate the issue.
• Image Stabilization Not Working:
  • Verify that image stabilization (VR/OS/VC on lens, IBIS on camera) is enabled in the camera's menu.
  • Some lenses or camera combinations may have limitations; consult the Fringer website for detailed compatibility.
• LaCA Correction Not Active:
  • LaCA correction is only supported for specific, optimized lenses. Check the Fringer compatibility list for your lens.
  • Ensure the adapter firmware is up to date.
