The RIG´s 2:13D40 / 2:13D50 / 2:13D60 & 2:13D100 are designed for Sony E-Mount models: ILCE-QX1, Alpha 5, Nex “wifi”, Alpha 6 Series & UMC-S3CA .
It can use any of the “fisheye”,”ultra wide angle” or “wide-angle”optics.
Its operation is simple and intuitively manual. The difference with respect to the nodal rotators is that the nodal points of each camera are not aligned with the NPP of the RIG, if not with the intermediate point of the hypothetical segment that joins both nodal points. (Patent Pending).
