Flash the option of turning the flash on/off has completely vanished off the settings in camera mode

The flash settings are on page 45 and 46 of the (english) manual.
When you are in smart mode, the camera will decide what the best flash option is. For the other modes where you can use the flash, like fill in flash, cheek page 46

Hello. If you're shooting in Auto mode and you have turned off the flash, your camera will remember that setting and the flash will not fire. If you switch the dial on top of your camera to another mode and then back to auto it should clear the setting and the flash should now fire, if needed. The other thing to try is to hold down the the flash popup/mode button while, at the same time, turning the rear control dial. You can watch your top display and the flash modes should cycle through different options.

check that you do not have the setting on burst as it will not be able to flash in this mode. when looking atthe screen about to take a photo, select menu, the first thingthat comes up is the mode, if it is in burst change in to normal and your camera should now have the option for flash or auto again :) good luck

Your menus will have options to be able to turn off the flash in certain modes.
The camera also has external buttons which will turn the flash on or off. Read your user manual.
The button which has the SET inside has four selectors. The right selector has a flash on/off button to turn the flash on or off. The flash usually will flash when set to flash all the time and not in AUTO mode. The AUTO mode may not allow you to turn off the flash. You probably have to choose another mode to allow the flash to be turned off.

Please note that:

1. You can not use the Flash when the Camera is set to Burst or Multi Burst mode.

2. You can not use the Flash when the ISO or Twilight mode is selected in the Scene Selection.

3. You can not use the Flash when mode dial is set to Movie.

4. Ensure that the battery is fully charged and the flash is turned ON.

Please set the Landscape mode or Snow mode or Beach mode in the Scene Selection and check if the flash is working.

5. Try initializing the Camera and check if it works normally.

NOTE: Initializing the Camera will reset the settings of the Camera to the factory settings including date and time. It will not delete any data saved in the Camera.

6. Please press the Menu button on the Camera. Then, select the SETUP menu and select the SETUP 1 option of the Camera. Then, select the Initialize option to OK.

7. Try to power reset the Camera and check if it helps to resolve the issue. I suggest that you reset the Camera by removing the battery from the Camera and inserting it after 1 minute.

8. If the issue still persists then the Camera requires service.


Good Luck!!!!!!!

When this camera is in "Auto" mode the only flash functions available are Auto or Flash Off - in order to get the option of "Flash On" for all pictures you have to put the camera in "Manual" mode - to do this:

-Set the mode switch to the camera icon
-Press the "Func./Set" button
-Use the left or right arrow keys to set it to Manual mode (its icon looks like half a camera with the letter M beside it)
-Press the "Func./Set" button again to save your mode change.

Now when you press the flash button and cycle through the choices there will also be a "Flash On" option.

If the built-in flash does not function, then the camera may be set to Auto and will only flash when taking pictures in poorly illuminated environments.
To set the camera to the Forced flash setting so it will flash regardless of the surrounding brightness, press the UP ARROW on the control button until a lightning bolt icon appears on the LCD screen.

If the Forced flash setting is already enabled and the flash is still not working, then the issue may be due to another camera setting. Even if the Forced flash setting is enabled, the flash will still not work in the following circumstances:
When shooting MPEG movies
When set to the Twilight mode
If an external flash is connected
If in the Burst or Multi Burst mode

Please touch the MENU option on the screen of the Camera.
Then, select the REC MODE under the MENU.
Then, select NORMAL under the REC MODE.

If you're not able to select the NORMAL under the REC MODE, try Initializing the Camera.

First, please touch the HOME on the LCD screen of the Camera.
Then, select the SETTINGS in the HOME menu.
Then, select the MAIN SETTINGS under the SETTINGS.
Then, select the Initialize under the MAIN SETTINGS.

If the issue still persists after performing the troubleshooting steps provided above service of the Camera is required.

It's required to physically examine the Camera to determine the exact issue at the service center.

I recently had the same frustrating problem. The top of the camera has a little black button that can change from continuous mode or single picture mode. It has to be on single picture mode to change the flash setting. After this is changed you can press the flash setting onthe dial and change the setting. I hope it works for you.

Press the up arrow on the back of the camera - that seems to be the flash mode setting - select which flash mode you want - you have to hit the down arrow once to see the flash off option which is a picture of a flash symbol in a circle. Then press ok. The flash should now not fire.

Because you have set the multi photo mode.
when you set it back to single shot mode, then the flash menu will change to more option to turn on flash.
it's because the camera can not charge the flash fast enough to do a few shot per second if flash is on.
This is the same as other digital SLR camera.
