# Lens files

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

Eight lens files can be written into a SD card as a single card file.

The following data is recorded to lens files:

- Title name

- White shading compensation values

- Flare correction values

- RB gain offset compensation values

## Creating lens files

### Adjusting white shading

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

### Adjusting flare

Adjusts the flare in the [CAMERA] menu → [LENS FILE ADJ.] → [LENS R FLARE]/[LENS G FLARE]/[LENS B FLARE].

### 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%.

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

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 to the [CAMERA] menu → [LENS FILE ADJ.] → [LENS FILE ADJ. MODE] → [ON].

Adjust so that the signal level of Rch becomes the same as Gch in the [CAMERA] menu → [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.
