combination is not suitable for your subject because you need
a faster speed, such as 1/ 250 second, to stop action.
In that
case turn the shutter speed ring until the index is at 250. This
leaves the exposure value 12
but automatically adjusts the lens
opening to
f / 4 and thus compensates for the faster speed.
On the
other hand, if you intend to take a picture which
requires good depth
of field, needing a lens opening such as
f / 16, rotate the speed ring until the index on the lens opening
is at 16. This changes the speed to 1/ 15 second. Ali exposures
1/
15 second and slower, including HB," demand that the cam-
era be on a firm support, for there is risk of camera movement
at slow shutter speeds.
If you want to set the exposure without reference to the
exposure values, be sure to set the shutter speed first and the
lens opening afterwards. If you reverse the procedure, changes
in the shutter speed will also change the lens opening, due to
the linkage between lens
opening and shutter speed rings.
