Note

This operation does not delete the scene file, lens file, and the information stored as the user data.

Lens file

The built-in memory of the unit can store 64 sets of lens files. On the SD memory card, 8 titles for 8 sets of lens files in a table (total 64 sets) can be written.

The following data are recorded on the lens file. Title name

White shading correction value Flare compensation value RB gain offset correction value

How to provide lens files

Adjustment of white shading

For the white shading adjustment, refer to [Adjusting the Lens White Shading] (page 112)

Adjustment of the flare

Using the menu operations, open the <LENS FILE ADJ> screen from the MAINTENANCE page and adjust the flare in the LENS R FLARE item, the LENS G FLARE item and the LENS B FLARE item.

Adjustment of RB gain offset

For correcting changes in white balance that may occur when replacing the lens.

1 Mount the lens as standard on the unit.

2 Shoot the grayscale chart with appropriate lighting

(2000 lx, 3200 K are preferable).

3 Set the WHITE BAL switch to the [A] position.

4 Adjust the lens aperture so that the white window at the center of the grayscale chart is about 80%.

5 Push the AUTO W/B BAL switch to [AWB] to adjust the white balance automatically.

6 Measure the signal level of RGB by using the waveform monitor (WFM).

7

8 Adjust the lens aperture so that the signal level of Gch is the same signal level as the one obtained in 6 above.

9 Using the menu operations, open the <LENS FILE ADJ> screen from the MAINTENANCE page and set the RB GAIN CTRL RESET to “ON”.

10 Adjust the signal level of Rch to be the same as Gch in the LENS R GAIN OFFSET item.

11 In the same way, adjust the signal level of Bch to be the same as Gch in the LENS B GAIN OFFSET item.
