Aiming to improve on the default design, the Leofoto NF-02 is a meticulously engineered support for Nikon AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR, AF-S NIKKOR 180-400mm f/4E TC1.4 FL ED VR, 300mm f/2.8, AF-S NIKKOR 500mm f/4E FL ED VR and AF-S NIKKOR 500mm f/4E FL ED VR. The NF-02 replaces Nikon's original lens collar foot and provides a lower profile and a lower center of gravity for a better balance. Two safety stops are located on the bottom of the foot, which prevents accidental lens release when a quick release receiver clamp is partially open.
