Interchangeable Focusing Screens
Nikon offers you a choice of 14 inter-
changeable focusing screens. The
advanced EC-B-type screen is supplied
with the F5 as standard equipment. See
list of all interchangeable screens.
For details on changing focusing screens,
see page 107.
•Focusing screens for F4, F3, F2 or F
series cannot be used with the F5.
•When a Multi-Meter Finder DP-30 or AE
Action Finder DA-30, which has built-in
exposure sensors, is attached to the F5,
EV level of the focusing screen may
require compensation depending upon
the focusing screen, lens, or telecon-
verter attached.
To compensate the EV level of a focus-
ing screen, use Custom Function #18.
(See page 90.) For required compensa-
tion value for each focusing screen, see
the instruction manual of the focusing
screen.
•Matrix Metering is available only with
screens EC-B, EC-E, B, E, J, A and L.
