Table 5: Maximum partial light output levels in stroboscopic mode

Example:

You intend to make a stroboscopic shot with 7 flash exposures at a frequency of 3 flashes per second.

Procedure:

After having completed the first six settings described in „Setting procedure for stroboscopic mode“, press the button N and then enter the number of exposures

-in this case 7 - with the „+“ or „-“ button. Then press the button f(Hz), followed by the entry of the flash frequency - in this case 3 - with the „+“ or „-“ button. The maximum possible partial light output level is automatically adjusted to 1/16. The partial light output level can also be manually adjusted to a smaller value.

☞The values specified in the tables only apply to fully charged NiCad batteries or to new high power alkaline-manganese batteries. For batteries that have been used it is necessary to adjust the next smaller main partial light output level (e.g. adjust 1/16 instead of 1/8)

to ensure that the number of flashes is achieved with certainty.

16. Technical Data

You have now adjusted the number of flashes = 7 and the flash frequency = 3; the maximum partial light output level of 1/16 has been adjusted automatically.

Table 6 shows you the aperture to be set on the camera.
