Minolta XG-A - Metering with the XG-A

20
FILM SPEED
Each film on the market has an ASA or DIN
exposure-index number to indicate its sensitivi-
ty to light . For correct exposure, the meter
must be set for the effective exposure index of
the film in use.
Setting film speed
To do this, lift up on the knurled ring of the
shutter-function selector and turn it until the
proper ASA indication appears centered in the
film-speed window and locks in that position
when the ring is released. Marks between
numbered graduations indicate ASA numbers as
shown in the ASA/DIN conversion scale at
right.
