About the AP-601 Replacement Lens Foot

It also has 1/4" and 3/8" tapped holes for mounting to non-quick-release tripod heads and monopods. All replacement feet feature the same dual safety stops and flash bracket compatibility as our lens plates.

About Wimberley Replacement Feet

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.

We use finite element analysis validated by empirical data when we design our feet. This process allows us to optimize the weight to stiffness ratio. Other manufacturers often reduce weight by removing material in ways that are convenient for the machining process or aesthetic design while ignoring stiffness performance resulting in rigidity below our quality standards.

Not compatible with most Manfrotto or Gitzo clamps
