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 597mm±5mm.
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 11.5Ev.
3. Ensure that the conversion lens is concentric with
the camera lens.
4-6. Installing the Jig Drivers on the PC
* As this device uses a USB interface for communica-
tions with the PC, the [USB Jig Driver] must first be
installed on the PC before the PC adjustment software
can be run.
* As the USB Jig Driver is the same for all models after
January 2001, this jig driver is already installed on the
PC. This driver software need not be installed on PCs
in which the USB device is already been adjusted.
<Step 1>
Insert the DSC jig driver setup floppy disk (ZJ00476-
101) in the floppy disk drive on the PC.
<Step 2>
Double-click on [setup.exe](Fig.D) on the floppy disk,
and follow the instructions on the screen to install the
jig driver.
The jig driver will be saved in [C:\Program Files\Fig].
(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%.
