The new Nikon replacement foot for the FL E-series lenses is finally here!
Tested and balance verified 100% on the:
1. Nikon 400mm F2.8E FL
2. Nikon 500mm F4E FL (you may want to consider the LF-N504LP for this lens if you are shooting with a lightweight camera)
3. Nikon 600mm F4E FL
4. Nikon 800mm F5.6E FL
This foot is rather taller and longer than we would normally design, but leave it Nikon to make this a challenge. The new E-series FL lenses have a large diameter lens hood and a neoprene cover which need to be cleared by the foot. The lens foot is also positioned far back on the barrel of the lens making it necessary to extend the foot a full 7" long to balance properly with light camera bodies.
This lens foot may fit older (or future unannounced models) of Nikon lenses. All Nikon lenses appear to have the same mounting pattern and screw size, so verification is mainly a matter of checking balance and clearance for the lens hood.
Tip: You don't need to balance your lens and camera with the silly neoprene cover! It must add nearly 1/2lb of weight to far end.
