The M Series Nadir Adapter from Nodal Ninja allows you to quickly shoot 90° down to take sharp nadir photographs. You just need to unlock the adapter, rotate it by 180°, and lock it again. You can then move the tripod to compensate for the displacement of the camera caused by the rotation of the adapter.
Additionally, for zenith photography, the adapter adds to the height of the vertical rail, providing enough clearance for shooting 90° up with many lenses. This compact adapter is sturdy and built with the structure of a rotator with fully lubricated bearings. It is suitable for anyone shooting an unobstructed down shot, especially if shooting HDR.
