*If no ND filter is attached, set it to [-].
Relationship between optical density and transmittance
| Optical Density of ND Filters | Transmittance |
|---|---|
| 0.3 | 1/2 |
| 0.6 | 1/4 |
| 0.9 | 1/8 |
| 1.2 | 1/16 |
| 1.5 | 1/32 |
| 1.8 | 1/64 |
| 2.1 | 1/128 |
| 2.4 | 1/256 |
Hint
- The [ND Filter] setting is configured manually, so it may not match the optical density of the ND filter actually attached.
- The value registered in [ND Filter] can be used as metadata when editing movie clips in the desktop application Catalyst.
