eras, the Speedlite 220EX
enables FE (Flash Exposure)
lock which locks the flash expo­
sure reading for the desired
area. The camera AE lock but­
ton functions as an FE lock but­
ton as soon as the Speedlite
220EX is recharged. Use FE
lock to obtain and lock the cor­
rect flash exposure reading for
the desired area of the picture.

shot while retaining the flash
exposure reading for optimum
flash exposure.
