# Lens file

Eight lens files are stored to internal memory on the camera.

Eight titles (total 64) of lens files can be written to SD memory cards with eight lens files saved as a single title.

The following data is recorded to lens files:

- Title name

- White shading compensation values

- Flare compensation values

- RB gain offset compensation values

## How to create lens files

### Adjusting the white shading

For details on adjusting white shading, refer to “White shading compensation”.

### Adjusting flare

Adjust flare by [LENS R FLARE], [LENS G FLARE] and [LENS B FLARE] in the main menu → [MAINTENANCE] → [LENS FILE ADJ.].

### Adjusting RB gain offset

Compensate for changes in white balance that occur when the lens is replaced.

Mount the lens to be used as a reference on the camera.

Shoot a grayscale chart under appropriate lighting (2000 lx or 3200 K preferred).

Set the <WHITE BAL> switch to <A>.

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

Press the <AUTO W/B BAL> switch towards <AWB>.

White balance is automatically adjusted.

Measure the signal level of RGB in the waveform monitor.

Replace the lens with the one to be used for creating the lens file.

Fine-adjust the lens aperture so that the signal level of Gch becomes the same as the signal level obtained in step 6.

Set [ON] in the main menu → [MAINTENANCE] → [LENS FILE ADJ.] → [LENS FILE ADJ. MODE].

Adjust so that the signal level of Rch becomes the same as Gch in the main menu → [MAINTENANCE] → [LENS FILE ADJ.] → [LENS R GAIN OFFSET].

Likewise, adjust [LENS B GAIN OFFSET] so that the signal level of Bch becomes the same as Gch.
