Bounce Flash in Manual Operation (Auto/
Manual Switch at the Back of the 199A Set to
M)________________________________________
It is ordinarily said that the light volume loss
in bounce flash is two f/stops when the
height of the ceiling is 2.5m. But remember
that this is only a guideline.
The bounce flash result is affected by various
factors including the color of the reflected
surface and the reflection efficiency.
Therefore, you should take test shots in
advance to obtain the necessary data.
The Wide Adapter is used when taking flash
pictures with 24mm and 28mm wide angle
lenses.
The flash angle is widened to cover the entire
picture. Therefore, it can also be used with
35mm and 50mm lenses. However, when this
Wide Adapter is attached, the light volume is
reduced.
Naturally,
therefore,
the
flash
coupling range becomes limited. For this
reason, the respective band in color around the
distance scale are not continuous lines. The
longer lines to the left are for your reference
when the wide adapter is in use. The procedure
for the 199A’s use is otherwise same.
