lenses are possible for lens numbers 9-16,
if necessary. For details, consult your Sony
dealer. (No data setting at shipping)
If using a lens not mentioned in the above
table
Shoot a white subject so that the entire screen is filled
with white. Try each lens number from 1 to 8 in order
and set to the lens number with which other colors
appearing on the upper and lower of the screen are
most minimized. It should be noted that it takes several
seconds until the results of a lens change is reflected
on the screen.
If an extender of the lens or a conversion lens is used,
first turn it off, then select the lens number. In this
case, care must be taken that color shading caused by
light sources will not be generated.
More accurate setting is possible using measuring
equipment, such as a waveform monitor.

Chapter 5 Adjustments and Settings
Adjusting the Aperture
Sensitivity
You usually need not adjust the aperture sensitivity
because lenses are equipped with aperture sensitivity
adjustment function.
In auto aperture mode, if hunting or response delay
happens, adjust the aperture sensitivity using the
aperture sensitivity trimmer.
Aperture sensitivity trimmer
(S or IG is indicated.)
You can see the aperture sensitivity trimmer when
removing the rubber cap on the front of the lens
driving unit. Use a small-screwdriver to turn the
trimmer. If you turn it clockwise, the sensitivity
increases, and if you turn it counterclockwise, the
sensitivity decreases.
It is recommended that you confirm the aperture
sensitivity after replacing the lens.
For more information, refer to the operating instructions for
the lens (or consult the lens maker).
