Nikon PC-E NIKKOR 24mm f/3.5D ED Manuel De L'utilisateur page 27

By rotating the tilt knob, the lens is tilted up and down (or right
and left, when the lens is revolved) ±8.5° to the camera body. By
tilting, you can obtain clear focus of the entire subject plane when
it is not parallel to the camera or can focus small areas of the
subject which are parallel to the camera (p. 195).
• After tilting, tighten the tilt lock release knob to fix the lens'
tilt position.
• Note that tilting the lens also changes the viewfinder image.
• Once the lens is tilted, neither the depth-of-field scale nor the
distance scale on the lens barrel can be used.
Revolving
This lens can be revolved up to 90° right or left. By revolving the
lens, the shift function can be changed to operate vertically, and
the tilt function can be changed to operate horizontally.
• Before rotating the lens, set the shift and tilt amount to "0" by
rotating the shift and tilt knob.
Note: When revolving the lens while using tilt and/or shift, be
careful to avoid nipping your fingers between the lens and
the camera body or scratching the camera body with the
lens. Failure to lock each knob can also have the same effect.
• Push the revolving lever and rotate the lens holding the square
parts of the lens.
• Click stops are provided in 30° steps both right and left.
At 30° and 60°, you can rotate the lens without pushing the
revolving lever.
