So recently when I was taking a picture I noticed a sound coming from the right side of the camera (the shutter button side).
I could hear it clearly when I press my ear against the thumb pad or better the right side of the rubber grip (where your palm would be).
It sounds like a cricket chirping (that's the best I could describe it as).
It's not a high frequency electrical noise (which I can hear from the bottom of the camera).
It's just loud enough to be vaguely heard during normal shooting (without ear pressed against) in a quiet room.
Definitely won't be able to hear it outdoors.
This is not an IS noise as it happens with a non-IS lens.
It only occurs with a lens mounted and occurs after a half-shutter press and release (not a full press).
The sound lasts about 5 seconds and during that 5 second period, if I half press and hold the shutter the sound goes away temporarily and restarts when I let go of the shutter.
Again in AF mode, the sound occurs after I half press and release my finger.
But weirdly in MF mode, the sound occurs only when I half press and HOLD.
What could this be?
If you have a 5D mark iii can you guys try it for me and see if you can hear it?
You have to be in a quiet environment and have your ear press against the right palm area of the rubber grip.
Thanks in advance and let me know!
