Hi all, I just purchased a Canon EF 16-35mm f/4L IS. I just used it for the first time today, just taking a few test shots around my house, and I noticed that when IS is turned on, I can hear a noise when the shutter button is pushed down slightly or after a shot is taken. Is this normal?
I also just bought the Canon EF 24-70mm f/4L IS and it's completely silent.
I'm sure I won't notice it as much when I'm shooting outdoors but just wanted to see if others have noticed the same thing specifically with the 16-35mm f/4L IS.
Thanks!
