The category, parameter, data type and operation type partition a 24 bit operation space.
Group ID Parameter Type Index Minimum Maximum Interpretation
Lens
0.0 Focus fixed16 – 0.0 1.0 0.0 = near, 1.0 = far
0.1 Instantaneous autofocus void – – – trigger instantaneous autofocus
0.2 Aperture (f-stop) fixed16 – -1.0 16.0
Aperture Value (where fnumber
= sqrt(2^AV))
0.3 Aperture (normalised) fixed16 – 0.0 1.0 0.0 = smallest, 1.0 = largest
0.4 Aperture (ordinal) int16 – 0 n
Steps through available
aperture values from minimum
(0) to maximum (n)
0.5
Instantaneous auto

0.6 Optical image stabilisation boolean – – – true = enabled, false = disabled
0.7 Set absolute zoom (mm) int16 – 0 max
Move to specified focal length
in mm, from minimum (0) to
maximum (max)
0.8
Set absolute zoom
(normalised)
fixed16 – 0.0 1.0
Move to specified focal length:
0.0 = wide, 1.0 = tele
0.9
Set continuous zoom
(speed)
fixed16 – -1.0 +1.0
Start/stop zooming at specified
rate: -1.0 = zoom wider fast, 0.0
= stop,
+1 = zoom tele fast
