Optimised Balance and Clearance for Nikon FL Telephotos

The Jobu Design LF-N604FL Replacement Foot is purpose-built for Nikon’s FL E-series super-telephoto lenses, delivering improved balance, enhanced clearance, and full Arca-Swiss compatibility in one robust design.

Engineered specifically for these large professional lenses, this replacement foot ensures stable handling and smoother operation when mounted on tripods, monopods, or gimbal heads.
