I have a sony A300 and the flash is playing up
I press the button to take a photo and the flash flickers 2-3 times before it goes off
Any Ideas !!

Default AutoFocus

I may be wrong, but I think the flickers have to do with the AF system. Some cameras have a red light to help the AF system get a good lock in low light conditions, but it seems that the Sony's use a few flickers of the flash.

Colorado Pilot is correct-

The Built-in Flash unit, when deployed, is used to assist in focusing.

If you go into your record menus, you'll find a choice for AF Illuminator on page 2. See the record menus on this page of our A350 review (and the A300 menus are the same):

http://www.steves-digicams.com/camer...-review-4.html


If you set it to "off", then the flash will no longer fire to assist with Autofocus (which I've found to be more trouble than it's worth anyway, often annoying subjects without really making much difference in the camera's ability to Autofocus).

Setting that feature (flash assistance for Autofocus) to off is one of the first things I do when using a camera that has it.

My little test with the a550 showed that one quick flash means the AF assist is on. If it's several flashes and then the shutter goes, it's red-eye reduction. That option seems to only be available in P mode.

It will keep flashing until it locks focus with most Sony models (which can be very annoying to subjects if taking photos in dim lighting). It's easier to leave it turned off and find an area with good contrast for it to lock on.

Ok. I tried it some more and, of course, you're right. The diff I see is the auto-focus assist flashes at a much slower rate than the red-eye reduction. I never use either anyway.
