With software version 1.7 and above it is possible to change the display of shutter speed to angular notation.
This can be done from the service menu (see your dealer for to get this feature enabled for you.)

The gain selections available from the switch on the side of the camcorder can be programmed in the user menu just like other camcorders.
A further option, available via the service menu, is to have the gain level displayed as an ISO / ASA sensitivity rating. Useful if you’re from a film background, but this feature should be used with care, as the displayed ‘speed’ of the camera does not take into account other factors affecting sensitivity:
•Shutter
•ND filters
•Range extender
•Transmission factor of the lens
These should all be added into the equation before attempting to expose pictures purely by using a light meter and the ASA rating of the camera.

Note that if you’re shooting at 25P you will probably choose to use a 50Hz shutter, and should therefore rate the cameras speed at half the above figures,
