Cine focus gear ring for Nikon Nikkor 50mm f/1.4.
This fits the second iteration of the 50mm lens with the new style rubber grip, sometimes known as New Nikkor. These can be Pre-/Non-AI, AI, or AI-S. The rubber grip is the two-row variant.

Low Profile—The rubber grip must be removed, as this gear ring replaces it. The front ring of this lens barrel can be removed so the gear ring can be slipped on in place of the rubber grip. This can be done without damaging the lens, and is easily reversible.
