Title: not working correctly
Review: The lens arrived packaged in the box. Took it out and put on my rebel. The manual focus ring initially moves smoothly then gets kinda stuck along the way and at the long end gives again producing a jerky and unpleasant effect. In auto focus there's a grinding sound as if there's sand in the mechanism and it does not focus fast. I was able to take a few pictures but the problems w/ both manual and auto focus is not what you'd expect from a 1000$ lens. I returned it.
Is the review positive or negative?
