When assembling the
conversion lens, take care to
ensure that the protruding
side is towards the subject,
and the flat side is towards
the camera lens.
(2)Setup for AF adjustment (Fig.B)
1. Set the distance between the conversion lens and
the tip of the lens to 900mm±2mm.
2. Use a light source to illuminate the AF chart. Ensure
that the luminance of the surface of the AF chart is
between 9.0Ev and 12.0Ev.
3. Ensure that the conversion lens is concentric with
the camera lens.
(3)Setup for Flash Adjustment (Fig.C)
Strobe adjustment is readily influenced by external light.
The periphery of the gray chart should therefore be as
dark as possible to minimize this influence.
Ensure that the gray chart is at a distance of 1000mm
from the camera reference face (*1). Use a Superior
Oxford Gray (No.22) chart, or a chart with reflectivity of
18±0.7%.

1. Set the distance between the Line Chart and the tip
of the lens to 932mm±2mm.
2. Use a light source to illuminate the Line chart.

chart is between 9.0Ev and 12.0Ev.
(Darken the lighting for the irradiation positioning
after suitable of the auto focus.)
