1. To remove the Nikon foot, use the M2.5 hex key tool that comes with the LCF-13 to completely remove the four Nikon mounting screws.
2. To install the LCF-13, 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 LocTite 242 for better security.

Why Choose a Replacement Foot 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.
