Be sure to make an inspection and adjustment, when dissembling and repairing the lens-barrel.

1. Check the resolution

By shooting the high-definition resolution chart (J63079), confirm that the TV lines are within the standard.

Standard for the TV lines:

1400 or more TV lines in the center ; 1200 or more TV lines on the periphery /4 corners

at both WIDE (18mm) and TELE (55mm)

(ref. The unit of resolution is based on TV lines, which are total number of black-and-white strips

distinguishable on the TV screen.)

Device: D100 camera, ITE high resolution chart (J63079), flicker-less fluorescent (AAA)

(a) Camera settings: Shooting-mode: Aperture-Priority Auto (A), Aperture: Full, Image quality mode

(FINE), Image size (FULL), ISO (200), Image sharpening (None)

Reset other settings (e.g. compensation) and shoot pictures.

(b) To avoid light irregularity on the chart, for either 2 units of Z light (Z-309)(J19124) or 2 units of 15W

inverter-type fluorescent stand, use fluorescent lamp color-rendering AAA (J19124A). Set them so that

reflected light does not directly come in shot images. (ref. Pic.1)

As for exposure, open the shot images via PHOTOSHOP, and make an exposure compensation so that

the value of RGV becomes 219±10 LSB, when the cursor comes to white parts of the images.
(ref. : Set the exposure compensation to about +1-step for becoming 219±10 LSB.)
