Genial is the effect but the removable disk. Although it is a known 200PL baseplate clamped, the cross Removable dadrunter but no Manfrotto 323 RC2 but a further development of this. Where the 323 that annoying pin has that always comes forward when pulling the lever and has to be manually reingedrücken again so that the next time clamping lever open from accidental is secured, the removable disk has on this joystick a revised version, in which the Pin automatically jumps back to the rear. So you do not think about it to push the security reasons himself back. Also, the lever folds completely to straight and is paralel to the removable disk. During normal 323RC2 the lever is despite the closed state so still at a slight angle projecting where you hooked behind fast times.
I do not know why Manfrotto not offer this version of the release plate einzelnd. It is superior to the normal 323RC2 in any case.
