Does anyone have a video of this sound? It's odd that out of all the issues here, no one has posted a video of the sound.
Go back one page (pg on this thread. There is a video of the sound, best starting around 16 seconds into the video. Mine is actually a bit louder (based on clicking sound vs zoom movement sound).
Yep, I just found it. I read through all pages, but just before finishing page 8, I posted. It was the last post on that page.
After listening to that video, I am good to go. Mine does not make that sound at all.
You are one of the lucky ones then!! I am getting my third replacement today from Adorama, hopefully it will be a good one. The last one I received was ridiculously loud clicking/ticking. You hear it all the way while zooming from 70-24mm. They were all 032 vintage BTW!!
