The Jobu Design Lens Collar Replacement Feet are designed to take the place of the factory foot on the collar of your Nikon or Canon telephoto lens. They feature an Arca-SwissTM style integrated foot, so no additional quick-release plates are needed. The replacement feet enable you to handle your lenses better on gimbal heads, such as the Jobu Design Black Widow series, by lowering the center of gravity so proper balance can be achieved.
*** Before ordering, please ensure that you are able to REMOVE the existing lensfoot on your lens. Most are removed with a 2.5mm allen key (except the Canon 400mm F2.8/600mm F4/800mm F5.6 which uses a M3). If the screws are glued or loctited in place, you should contact your local Canon or Nikon service centre for assistance.***
