NEUTRAL DENSITY (ND) RANGE
The table below provides the available fraction values, optical density values, and stop losses. The values
provided are in increments of 1/2 and 1/3 stops.
The available ND range is based on the currently selected shutter type.
ND Only: The available optical density range for “ND Only” is 0.48 to 2.40 (1.60 to 8.00 stops).
Soft: The available optical density range for “Soft” is 0.48 to 1.20 (1.60 to 4.00 stops).
Square: The available optical density range for “Square” is 0.48 to 1.20 (1.60 to 4.00 stops).
