Pop-Up Flash

Discussion in 'Canon EOS' started by alison_warren, Aug 17, 2011.

  1. I just bought a Canon Rebel EOS T3i last weekend, and tried it out again today. When the flash was "preparing", it made a small buzz sound, almost like a current.. I didn't think it sounded good--common sense would probably suggest it's not great... But wasn't sure if that was normal for this camera or not? It still takes the pictures just fine, but the small buzz sound before the flash goes off has me a bit concerned? Suggestions? Insight!? Thanks for your help!

    When it was "buzzing" was it also "flashing"?
    And if it was doing both, then was the lens also attempting to achieve Auto Focus?
    If yes - then that is all OK - it is the Flash "AF Assist" read p 86 for an explanation.
    Read p 255 for info about the Custom Function, which controls it.

  3. Maybe it's just the sound of the capacitor being charged. This "buzz" (or high whirring sound) is common with add on flashes although I've not heard it with built-in flash units. It's not uncommon to hear some noise, the IS mechanism can be heard as well.
     
  4. Merely means you have doggie ears and can hear the squeal of the capacitor charging up the popup. It's much softer than a shoe-mount unit but is clearly audible in a quiet room (at least to me, maybe not to Dead fans with blown eardrums).
     
  5. I'll place money on it being the AF assist as William has pointed out. This is the default behavior of the camera and there is nothing wrong with it.

    Haha.
    Well, with the score line 2 votes for the Capacitor and 2 votes for the AF assist . . .
    I hope the OP comes back and tells us the answer, as I thought of the capacitor but the word "buzz" is synonymous with the "a bee" . . . the capacitor has an high pitched, but low level "squeal" . . .
    Perhaps we need a facility to post audio bites.

  7. Next we'll be trying to emulate the noise -- like on Car Talk...

    ha-ha
    . . . my sister-in-law, also a Sagittarian, ripped the Satellite Navigation system out of her BMW because she, (quote) "couldn't stand the sheila’s voice, worse than the shelia in the Lift" (Lift = "elevator" in a department store).

  9. I hope the OP comes back and tells us the answer...​
    One-post members rarely do and, instead, usually leave us suffering with an unsolved mystery: buzz, squeal or zap...

    :)
    [I giggled at "doggie ears" too]
     
  11. Almost 99% sure it's AF. :) Thanks for your help, everyone! I appreciate it!
     
  12. I was just being paranoid. I'm a newbie! It was flashing when buzzing so I'm sure it's the AF-assist.
