Camera Setup

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:

• Turn the Mode Dial to M-REC.
• Press the MENU button twice, followed by the left button (to use the tab), down button (to move to the setup menu), and right button to bring up the SET-UP 1 menu as shown in the left image below. Then, press the down arrow of the multi-selector a number of times until the SET-UP 2 menu appears (below right).

• Once you enter the SET-UP 2 menu, the first item is Speedlight Opt Use the right arrow of the multi-selector to select Speedlight Opt. Then, two options appear as shown in the left image below. The first option, Variable Power, has been discussed on 995 internal flash page (i.e., Using Variable Power). The second one, Int Flash Off is for turning the external flash on or off. Use the down arrow of the multi-selector to highlight Int Flash Off as shown in the right image below.

• Use the right arrow of the multi-selector to select Int Flash Off. Two more options appear as shown in the image below, namely: Off and On. If Off is selected, the internal and external flashes will both be active. In other words, the internal flash may fire in case illumination is insufficient. The On option simply turns off the internal flash. Because we want to turn off the internal flash, use the right arrow of the multi-selector to highlight the On option, followed by the right arrow to make a selection.

  Yes, I am correct. Choose the On (resp., Off) option to turn off the internal (resp., on) the internal flash.

• Once the above steps complete, press the MENU to return to the M-REC shooting mode.

  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.

External Flash Settings

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:

Icon		Meaning
Ctrl Panel	LCD
		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.
