Here is a video using the lens that may explain why I think its broken: https://www.youtube.com/watch?v=R-QzxfUaTZ0 As title says, I was finally able to save up $1200 to buy my first big lens. Bought it from an ebay camera company that's located in Ohio, they go by the name of ColumbusCameraGroup. I felt good about the purchase because they had really good rating (32,000 with 99.4% positive) and the lens seemed in nearly perfect condition. I got it today after a week, which seemed more like a year. I start taking pictures with it right away and did some video to try it out. The pictures came out pretty smooth but noticed when zooming in and out during video i started hearing these scraping noises so I decided to look into it a bit more by taking it to my local camera shop to have it looked at. The guy at the camera shop ended up taking a few test shots and moving things around to make sure everything works, and he ended up telling me the VR doesn't work and there was no sense in having it fixed since it would cost a lot. I'm not sure how my VR doesn't work when I hear the inside motor turning to focus. I turned VR off as well and it made no noise/motor wasn't going, then, I turned it back on and the interior motor starting working again (does this mean VR does work?). To sum it up, I'm not sure if my lens is broken or what the scraping noise is, could someone help me on what to do? Thank you!
