Really Right Stuff LCF-10 with LC-A10 for Nikon 300mm f4 AF-S lens mount_Bronica ETR I'd wager to sayThe Really Right Stuff LCF 10 and LC A10 together are a replacement for the OEM tripod mount on Nikon's 300mm f4 ED AF S lens but the LCF 10 by itself can also replace the foot on the Nikon AF S 70 200mm AF S I and II. Very well made, as you may expect, and in excellent condition.
