• Press <->, “-0.3” means 1/3 step, “+0.7” means 2/3 step.
•To cancel flash compensation, set the amount to “+0”.
High-Speed Sync

shutter speeds. This is convenient when you want to use aperture priority for
fill-flash portraits.

With high-speed sync, the faster the shutter speed, the shorter the
effective flash range.
• Multi-strobe mode cannot be set in high-speed sync mode.
