Hey guys, I've had this lens since August and it's been pretty decent. I went out to shoot the stars last night and when I got everything setup, I switched to manual focus to get the stars in focus. I began to turn the focus ring and nothing happened. I fiddled with it for about 20 minutes and had no luck. My autofocus worked fine, but manual focus would not adjust anything. I tried turning the camera off, took the lens off andreatttached, tried to manually adjusting around mode. No luck. Any ideas as to why this just quit working all the sudden?
