Hey everyone, I just got a brand new Sigma 18-35 1.8 Nikon mount and noticed that when I rotate the focus ring, I get 3 "stops" with audible clicks. It's not a smooth and quiet rotation of the focus. So naturally my question is does anybody else have it, and if that's the case, why nobody talked about this in their reviews? I feel this is not working well for run and gun situations when the audio mike is mounted on the camera. Very disappointing! I called Sigma tech support and they told me this was very much normal. It seems Sigma focus rings click... Do you have the same experience with yours?
