Coupling Lever Lock/Release Operation - Nikon F2AS Photomic Instruction Manual

Coupling Lever Lock/Release Operation
The camera's Photomic finder is fitted with a meter
coupling lever that provides for coupling between the
finder's metering circuit and the lens' meter coupling
ridge. When the camera body is used with lenses offering
automatic maximum aperture indexing, the lever remains
in the normal position. However, when the camera body
is used with lenses and/or accessories not provided with
this feature, the lever must be locked up to permit ex-
posure measurement via the stop-down method. To lock
up the lever prior to mounting the lens, simply push up-
ward and to the right until the lever clicks and locks into
position. To release the lever for operation with a lens or
accessory capable of automatic maximum aperture
. indexing, simply slide the coupling lever release (located
just above the lever) to the right until the lever returns
to its normal lowered position ; then, mount the lens as
explained previously.
