Switch your lens' original foot for a better-balanced design with the Lens Foot LN-60 for Select Nikon Lenses from Markins that is made for the Nikon AF-S 400mm f/2.8G ED VR, 500mm f/4G ED VR, 600mm f/4G ED VR, and 800mm f/5.6G FL ED VR Lenses. The foot is constructed from Duralumin and hard anodized for a scratch-resistant surface. Dovetails on the bottom of the foot make it compatible with Arca-type heads or clamps, and 1/4"-20 and 3/8"-16 sockets under the foot can be used to mount directly on a monopod or tripod if no quick release system is present.
