How to use EX-series Speedlites for fully automatic E-TTL flash photography with the DCS 500 Series camera

1Turn On the camera’s Main switch, then turn on the flash.

2Make sure the flash is set for Normal Sync. Please refer to the Speedlite instruction book and verify that the flash ready light is illuminated in red (indicating a full charge).

3Make sure the EF lens is set for AF operation. (Check the focus mode switch on the lens.) This step ensures that E-TTL flash exposure control will be concentrated on the active focusing point.

☛When the focus mode switch on the lens is set for MF or M, E-TTL flash exposure control will be averaged across the entire picture area.

4Set the camera to Program mode (P) for fully automatic exposure.

5Select a focusing point using the Focusing Point Selector button and Main dial, or set the camera for automatic focusing point selection (described in the next chapter) and focus the subject by pressing the Shutter button halfway down. DO NOT recompose.

6Press the Shutter button completely to capture the image. Correct flash exposure of the subject located at the active focusing point during the exposure is assured when the flash exposure confirmation signal lights up on the EX-series Speedlite (described in the next Chapter.)

What is Flash Exposure Lock (FE Lock)?

Flash Exposure Lock (FE Lock) adds AE lock and spot metering functions to flash photography with EX-series Speedlites and the DCS 500 Series camera. With FE Lock, the EX-series Speedlite’s preflash fires when the camera’s AE Lock button is depressed, storing metering and AF data for up to 8 seconds. This provides enough time for adjustments. Not only can the shot be recomposed, but the background exposure can also be altered for maximum creative control. FE Lock is extremely useful when you wish to recompose after focus lock or to place the main subject in a part of the picture area that is not covered by one of the focusing points. It can also eliminate potential exposure errors caused by unwanted reflections from highly reflective surfaces like windows or mirrors.
