Set the image.
(1) Shoot a solid white sheet of paper.
(2) Set the lens iris to manual and adjust the
iris so that a zebra pattern fills the entire
viewfinder screen.
• When the piece of paper is unevenly lit,
the zebra pattern will not cover the entire
screen. Adjust as required.
• Make sure that the white paper is
not exposed to multiple light sources
(example, fluorescent lighting or halogen
lamps) of different color temperatures.

lamps tend to flicker and should not be used for
this adjustment.
• Adjust the light source if the lens iris is out of
the range between F4 and F11.
• Make sure the electronic shutter is set to off.
