Warnings of Inconect Operation in
Stopped-down Photography
Two problems can arise if you use the
camera incorrectly
in
the stopped-down
mode. The firs t proble m occurs if the
stop-down lever of the camera is locked in
before you mount the lens. If you expose a
frame in this situaLion, it will be incorrectly
exposed due Lo incorrec t coupling of the
aperture ring. To prevent this, before you
moun t a lens, m ake sure there is no red dot
beside the stop-down coupling lever inside
the camera body. The
r~d
dot is very con-
spicuous and appears only when the stop-
down lever is pushed in.
The secon d problem arises if you push in the
camera's stop-down lever and, before t aking
a shot, release the stop-down leve r and
return the lens aper ture ring to the "A"
mark. If you
then
try
to press the shutter
- 64-
button, you will notice that neither it nor
the film advance lever will operate. What's
m ore, this is when the " EEEE
EE"
mark will
flash in the viewfinder whether th e view-
finder display switch is turned off or not.
This appeal's L o b e a distressing situation, but
it is very easily corrected. P ush the film
advance lever int o its retracted position close
to the camera body. The multiple exposure
lever is underneath. Push it to the le ft. Now
turn the film advance lever. With this opera·
tion, the camera will work in the norm al
way.
