After attaching the AS-E900 adapter, turn the flash to the ON position and set the flash mode to TTL. The flash should not be set to the stand-by mode (i.e., STBY); otherwise, it may turn off unexpectedly. If it is possible, the illumination angle should be set to 28mm or wider.
You have two choices. You can either allow both the external flash and internal flash to fire. Or, you can turn off the internal flash and only use the external one. To turn off (i.e., disable) the internal flash, follow the procedure below:
|Yes, I am correct. Choose the On (resp., Off) option to turn off the internal (resp., on) the internal flash.|
Note that once this option is chosen, it will stay there even after turning off the camera. Therefore, you need to go through the above procedure again to reverse the setting..
To enable the internal flash, follow the above procedure to select the Off option.
|Do forget to raise the internal flash in order to use the external one.|
Similar to the internal flash, there are four different external flash settings available. Each flash setting is indicated by a pair of icons shown on both the control panel and LCD monitor. The meaning of each flash setting is shown in the table below. Please note that the internal flash icon (i.e., the right icon of the two) means Flash Cancel because it is turned off. If the internal flash is not turned off, the icons shown on the control panel and LCD monitor display only the status of the internal flash. The four external flash modes are:
|The Auto mode. When illumination is poor, the external flash fires automatically.|
|The Auto with Red-Eye Reduction mode. Activate the Red-Eye Reduction mode.|
|The Anytime Flash or Fill Flash mode. Force the external flash to fire. This is useful for fill flash.|
|The Slow Synchronization mode. Activates the Slow Synchronization capability of the external flash.|
