6. 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.
• Stroboscopic flash cannot be used with the EOS 750 and EOS 850 cameras.
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.
