Using an Externally Mounted Flash (Sold Separately)

Speedlite 220EX, 270EX, 430EX II, and 580EX II

The maximum flash synchro shutter speed is 1/250 second.

The flash will automatically adjust its output when [Flash Mode] is set to [Auto]. Flash exposure compensation and safety FE can be set when the flash is set to auto exposure. However, when performing flash exposure compensation with the camera, make sure to set the flash exposure compensation on the flash to [+0].

The flash output can be adjusted on the camera or the flash if [Flash Mode] is set to [Manual]. With Speedlite 220EX and 270EX, settings cannot be made on the flash. In D mode, you can set the flash output with the camera even if the flash unit is set to E-TTL automatic flash exposure compensation. [E-TTL] will display on the flash, but the flash will fire manually. Also, if the flash compensation value is changed on the flash, the flash output will also change.

Settings available on the camera are as follows.
