The nadir adapter allows the user to take sharp nadir (90 degree down) shot quickly. It is as simple as unlocking the adapter, rotating it by 180 degrees and locking it again. User then moves the tripod to compensate for the displacement of the camera caused by the rotation of the adapter. Taking sharp nadir shot is then just a matter of pressing the shutter release button. Moreover, it adds to the height of the vertical rail, providing enough clearance for zenith (90 degree up) shot for many lenses. Built with the structure of a rotator with fully lubricated bearings, it is as sturdy as a rock. It is compact and acts as an integrated part of the modular system. It is a must have accessory for anyone shooting an unobstructed down shot, especially important if shooting HDR. Tutorials Credits go to hindenhaag - Use of Nadir Adapter.
