The Leofoto NF-05L Lens Foot is an improved replacement for select Nikon lens collar feet for a lower profile and improved balance. This is a meticulously engineered aluminum support with built-in Arca-type dovetail mounts featuring 1/4"-20 and 3/8"-16 receivers as well as a QD socket for quickly attaching a compatible strap or sling. Two safety stops on the bottom of the foot prevent lens release. The extended length of this foot is ideal for longer lenses.
