[F9] : AF-Sensor Adjustment

< Setup for AF-Sensor Adjustment>
(1) Prepare as follows using non-defective equipment.
(2) Mount the camera on a tripod, and place the S9000/S9500 AF-1mV Chart (for 1005mm) at a distance of 1005mm from the
front face of the AF-Sensor window.
(3) Set the camera power lever to the Photography mode, and display the through screen on the TV monitor.
(4) Set the lens position to TELE END.
(5) Adjust the camera position so that the AF target symbol (yellow) displayed on the TV monitor overlaps the 'Red circle'
symbol near the center of the 9000/S9500 AF-1mV chart (for 1005mm).
(6) Attach an OHP sheet to the TV monitor.
(7) Place a mark in the center of the target mark displayed on the TV monitor.
(8) Draw a circle on the OHP sheet with the marked point as the center.
The size of the circle will differ from the TV monitor used. The circle sizes for the various TV monitors are as follows.
14" to 16" : 5mm radius
17" to 19" : 6mm radius
20" to 21" : 7mm radius
(9) This completes preparations for AF-Sensor Adjustment.
<Environmental Settings for AF-Sensor Adjustment>
(1) Set up the conversion lens (f=900 mm) and the two types of AF-Sensor chart as shown below.
(2) Illuminate the AF-Sensor chart (1000mm) using one or two light sources. Adjustment is impossible if the illumination does
not match.
The distance between the light sources and the AF-Sensor chart must be approximately 5cm.
AF-Sensor chart reflective luminance : 7.0Ev to 9.0Ev
(3) Place the conversion lens concentric with the front face of the AF-Sensor window.
(4) If the center of the conversion lens and the center of the AF-Sensor window are significantly misaligned, an error will occur
during AF-Sensor Adjustment, and adjustment will become impossible.
