The Jobu Design Lens Collar Replacement Foot for the Nikon 600F4/400F2.8 is designed to take the place of the factory foot on the collar of your lens. It features an Arca-Swiss style integrated foot, so no additional quick-release plates are needed. The replacement foot enables you to handle your lens better on gimbal heads, such as the Jobu Design Black Widow series, by lowering the center of gravity so proper balance can be achieved.

• Features both 1/4" and 3/8" mounting holes on the bottom of the foot
