It shouldn't be a problem unless you're continuing to depress the capture button....
It's great for catching just the right shot. However, for those of us who have learned to stabilize the camera by holding down the shutter button instead of tapping it, burst mode can result in a lot of unexpected pictures.
I noticed this as well. I used to hold the button down and once the focus locked in, I would release and the picture would take. Out of habit I have gone to do that several times and ended up with a slew of pics. But, I will say that I do like burst shot and it has given me a very solid pic I might not have otherwise gotten on several occasions.
I dont like it. Apple! Give us an update to turn it off!:concern:
