Using The Tripod Collar Ring - Nikon NIKKOR Z 180-600mm f/5.6-6.3 VR Reference Manual

Using the Tripod Collar Ring

Attach tripods to the lens tripod collar, not to the camera.
Rotating the Camera
Attaching tripods to the lens tripod collar rather than to the camera allows the
camera to be rotated as described below to take pictures in "tall" or "wide"
orientation while a tripod is attached.
1.
Loosen the tripod collar ring attachment screw (q) until
the lens can be rotated.
Be careful not to over-loosen the tripod collar ring. The screw could pop
out unexpectedly and cause the lens to fall, potentially resulting in injury or
product malfunction.
