Re: EOS-300D Flash

Your flash is acting to 'fill' for you. fill lighting can be a benefit. if you don't want it, see settings menu to turn off flash until you need it. not difficult and worth knowing how to make simple routine setting adjustments.
good luck

Hi, I have a Canon EOS Digital Rebel, and as of recently, it has been doing this thing where, on certain settings, i will go to focus the image, and when i click down all the way to take the shot, the...

Hey Lackster,
Error 5 is a problem with the flash. Long story short it thinks there is an external flash attached even though the mechanical pop-up still works. It is repairable.

Please let me know if you have any more questions.

Thank you.

The picture is half black

Half black would suggest that our camera flash and speed are not sycronised.try a slower speed when taking flash/indoor shots when in the creative mode eg,P- TV- AV- etc

How do i stop the flash popping up on a canon eos 350d even when taking a photo outside in bright light...I am using the auto setting

Try using the "no flash" setting. It is still completely auto, it just won't fire a flash. It is the setting that looks like boxy "no sign" over a lighting blot on the settings dial, it is also the last setting.

Hope this helps!

My EOS 400D flash sometimes pops up in bright daylight in full auto mode. I sent it back to Cannon who returned it saying no fault found. I then began to think that the problem was the way I held the...

In full auto mode, the camera tries to use fill flash, when it detects a backlit scene (e.g. a person in front of a window). So this is not a bug, it's a feature!
If you don't want the flash to fire, you can push it down and still take the shot. If you want to take control yourself, use one of the creative modes (e.g. P or Av).

This has nothing to do with obstructing a sensor, as the camera meters through the lens (only). What you are referring to, most likely is the red eye reduction light / self timer indicator.

Flash will not close on Canon EOS 7D

If you shoot in the Basic Modes (any of the modes with icons like Portrait, Landscape, Sport, etc), the flash will pop up automatically if there isn't enough ambient light even after pushing it down to close it. To shoot without auto flash, use one of the Creative Modes like P, Av, Tv, M etc. If your problem is that the flash springs back up again when you try to push it down, the catch may be faulty. You may want to consider taking the camera to an authorised Canon repairer.

Bottom 2/3 of photo is black

It sounds like your autofocusing mirror is loose and obstructing the shutter.

How to switch on Auto Flash in Auto mode

Put the camera in "P" and press the flash button above the lens release. If the flash pops, than you probably just have too much light to need it when you are in auto. The flash button is not active in auto so if the xti doesn't want the flash in auto, u can't make it fire. If the flash button does not make the flash pop in "P", search this site for another post about flash not working and u will find that this could be the flash deactivation button in the hot shoe sticking. Not likely though with a new camera unless u have had a speedlite mounted alot.--

I found the answer and fixed my flash. Look on

This will describe how, if you have been using a speedlite alot, than the little tab under the shutter release side of the hot shoe can get bent down thus constantly pressing down (toward the bottom of the camera) the small button which deactivates the pop-up1.gif flash even when the speedlite is not attached. Just bend the tab up a little with a jewler's screwdriver, turn the camera off and on and voila!! Fixed!!! Dan describes pushing the tab down, but on the xti, the tab needs to be bent up to release the flash deactivation switch and fix the problem. Thanks to Dan D on photonet for saving me a service call.
