3.2 Program Wizard "speed mode" (continued)
In "quality" mode the VR Drive stops and releases the camera in every position.
In "speed" mode the VR Drive releases the camera "on the fly" without stopping in every
position.
"quality" mode:
stop + release
The faster the total rotation time, the faster the shutter speed of the camera
needs to be, otherwise the images will be blurred (unsharp).
The following table indicates the maximum shutter speed required for different
rotation times. For example, when setting the rotation time to 6 seconds, the camera shutter
speed needs to be 1/1500 sec. or faster (1/2000 s, 1/3000 s, ...):
Rotation time (X, 360°)
6 s
10 s
20 s
When a fast shutter speed cannot be reached (i.e. under difficult lighting
conditions), it is possible to compensate in the following way:
• Increase ISO/ASA
• Open the aperture (use a lower f-stop) and save the image at a larger resolution –
the lower depth of field can be compensated by compressing the resolution of the
images
• Reduce the rotation speed
