Wimberley P652

These custom low-profile replacement feet replace the factory foot on the rotation collar of your lens and also serve as the Arca-Swiss style quick-release plate for your lens. No additional quick-release plate is needed. It makes your lens handle better on a conventional tripod head, such as a ball head, and also makes it easier to pack. For 600mm f4 AF-S. Lowers the overall height of the lens by about 1"". (Use AP-452 for 600mm f4 AF-S II)
