Changing The Lens - Nikon F2AS PHOTOMIC Instruction Manual

CHANGING THE LENS

To remove the lens from the camera body, press the lens re-
lease button and, holding the button depressed, twist the lens
clockwise as far as it will go. With this action, the lens will
come loose and can be lifted out.
To mount a lens fined with a meter coupling ridge, per-
form the following: Check that the finder's meter coupling
lever is released (see "Coupling Lever Lock/Release Opera-
tion" on page 39 for details); position the lens in the camera's
lens mounting flange so that the mounting indexes on the
lens and camera body are aligned; and, then, twist the lens
counterclockwise until it clicks and locks into place. These

steps provide for full mounting of the lens, while simulta-
neously indexing the lens'maximum aperture setting to the
camera's Photomic finder.
To mount a lens not fitted with a meter coupling ridge,
first lock the meter coupling lever in the up position (again,
see "Coupling Lever Lock/Release Operation" for details).
Then mount the lens and lock it into position as explained
previously. For operation with lenses not fitted with a meter
coupling ridge, stop-down measurement (as described on page
28) is required.
