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!
