Jobu Design's Low Profile Replacement Foot--Nikon 500mm f/4, 300mm f/2.8, 200-400mm is designed to replace the factory foot on the collar of a Nikon 500mm f/4, 300mm f/2.8, or 200-400mm f/4 lens. It has an Arca-Swiss style integrated foot, so no additional quick-release plate is required. This replacement foot allows you to better handle your lens on gimbal heads by lowering the center of gravity for proper balance.
Made from aircraft aluminum with a black anodized finish
Features both 1/4" and 3/8" mounting holes on the bottom of the foot
Fits the Nikon 500mm f/4, 300mm f/2.8, and 200-400mm f/4 lenses (it does not fit older manual focus lenses)
