8. Stroboscopic Flash

With stroboscopic flash, a rapid series of flashes is fired. It can be used to record multiple images of a moving subject in a single photograph for later study.

You can set the firing frequency (the number of flashes per sec. expressed as Hz) from 1 Hz to 199 Hz. The firing frequency can be set in 1-Hz increments from 1 Hz to 20 Hz, in 5-Hz increments from 25 Hz to 50 Hz, and in 10-Hz increments from 60 Hz to 199 Hz.

Up to 100 flashes can be fired continuously. This maximum varies depending on the flash output and firing frequency. See “Maximum Continuous Flashes” on page 122.
