My apologies for asking a stupid question. But hopefully I'll be able to get some straight answers.
I never used the 40D built-in flash. Didn't like it and since I had the 580ii & 420, I never really bothered. But now that the 7D has the built-in wireless feature, I decided to test it out. Now with the flash popped up on the 7D, the camera does a pre-flash/flicker. The flash/flicker doesn't bother me. But it's accompanied by a "buzzing" sound.
So my stupid question, is this "buzzing" sound normal for the 7D? Any other fellow 7D users find this to be the case for your camera?
Thanks in advance.
