This is the Haoge LF-Z72 lens foot. I am selling it because I have replaced my lens. It is Arca-Swiss compatible, allowing for quick attachment to tripods and monopods with a single touch. I used it to replace the lens's original tripod collar, so there are some scratches and scuffs on the bottom, but there are no functional issues. It is compatible with Nikon Z lenses. Z 70-200 Z 100-400 Z 400/4.5 Z 600/6.3 Please note that this is a used item and is non-refundable and non-returnable. Thank you. ↓ The following is a quote from the manufacturer ↓ The Haoge LF-Z72 lens foot is a replacement foot for Nikon NIKKOR Z 100-400mm f/4.5-5.6 VR S, Z 70-200mm f/2.8 VR S, Z 400mm F4.5 VR S, and Z 600mm f/6.3 VR S lenses (Z mount).
