Note
This operation does not delete the scene file, lens file, and
the information stored as the user data.
The built-in memory of the unit stores eight sets of lens files.
On the SD memory card, eight titles for eight sets of lens
files in a table (total 64 sets) can be written.
The following data are recorded on the lens file.
z Title name
z White shading correction value
z Flare compensation value
z RB gain offset correction value
For the white shading adjustment, refer to [Adjusting the
Lens White Shading] (page 112)
Using the menu operations, adjust the flare in the LENS R
FLARE item, the LENS G FLARE item and the LENS B
FLARE item. These menu items are found in the <LENS
FILE ADJ> screen on the MAINTENANCE page.
Example of the chart for flare adjustment
For correcting changes in white balance that may occur
when replacing the lens.
1 Mount the lens to memory the lens file 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 Adjust the lens aperture so that the signal
level of Gch is the same signal level as the
one obtained in 6 above.
8 Set the LENS FILE ADJ MODE to ON.
The menu item LENS FILE ADJ MODE is found in the
<LENS FILE ADJ> screen on the MAINTENANCE page.
