Just mounted the new Movi MR model kit on M10. It is quite different from the model shown in original Movi MR Manual. It has tubes legs and doesn't have the octo suspension plate which I guess is to be used only with Cinestar. As we are going to use it on Alta it is not required, I suppose. But comes two spare tubes with the kit. One that seems to be used to replace rear pan adjustment tube giving it longer travel for heavy camera adjustments. But the other tube has a kind of rail on it. Any guess what is used for?
