Using the Optional Dedicated External Flash FL-40

The dedicated external flash FL-40 increases the amount of light and can illuminate subjects which are beyond the range of the built-in flash. You can also use the dedicated external flash to bounce light onto the subject from another direction, allowing more variety in the use of lighting. The dedicated external flash can be mounted on the hot shoe on top of the camera or mounted on the optional flash bracket attachment. With the dedicated external flash, you can use flash control compensation and select the flash mode, just like you can with the built-in flash. (➞ 90)

If you want to use only the dedicated external flash, just push down the built-in flash.

To use the dedicated external flash and built-in flash together

With the built-in flash you can also use the dedicated external flash to bounce light onto the subject to create a catch-light effect to light the eyes of the subject more naturally. When the built-in flash and external flash are used together, the built-in flash provides about half of the light emitted from the dedicated external flash. When you use the external flash to bounce light onto a subject, in some cases the intensity of the external flash could be insufficient, even with the range for flash shooting, please remember that you may not be able to achieve the correct exposure.

To set the flash mode for the FL-40

When the dedicated external flash is mounted on the camera, the camera automatically sets the flash for TTL-AUTO, and the intensity of the dedicated external flash can be controlled from the camera. With the mode dial set to M (Manual mode), you can select MANUAL on the dedicated external flash. This allows you to set the guide number on the dedicated external flash, and select the aperture on the camera for taking a picture.
