Some collared, telephoto lenses have a foot than can be removed. If your lens has this option, choose one of our foot replacements instead of a lens plate. A replacement foot with built-in-dovetail mounting will be lighter, lower in profile, and provide the best possible stability for your lens. Really Right Stuff foot replacements are precision machined from solid blocks of 6061-T6 aluminum and are fully compatible with any Arca-Swiss quick-release system. This foot replaces the Nikon lens collar foot on the following Nikkor lenses:
AF-S 500mm/f4 ED-IF lens
AF-S VR 500mm/f4 ED-IF lens
AF-S VR-II 500mm/f4 ED-IF lens
1. To remove the Nikon foot, use the M2.5 hex key tool that comes with the LCF-16 to completely remove the four Nikon mounting screws.
2. To install the LCF-16, use the four original Nikon M3 screws and secure the Really Right Stuff foot to the lens collar.
3. If your mounting screws loosen over time, consider using a drop of medium threadlocker, such as Vibratite or Loctite 242 for better security.
