The Wimberley C30 quick release adapter accepts Arca-type quick release plates from Acratech, Arca-Swiss, Foba, Graf, Novoflex, NPC & (of course) Wimberley. From head-to-toe it is a superior, exceptionally engineered design which will yield many years of reliable, heavy-duty use. The C30 is long enough to hold any lens/camera combination like a vise grip. The C-30 is for those who wish to retrofit an old-style Wimberley Head, replace a damaged C-30, or have an application that requires a longer clamp.
