I just got it and I don't want to twist any harder or something is going to break. I already heard a creak. Has anyone else had this problem? SOLVED But holy hell is that tight! In normal situations I would get in there with a micro file or else press on the spring connectors on the inside of a camera but obviously I can't go that route. I actually touched a bit of oil to a plastic toothpick thing and touched it to the lens connectors and after putting it on the camera wiggled back and forth, back and forth and finally she seated. Uggh! UPDATE: So I painstakingly pulled the lens off and found a shred of metal. Do not really want that on the sensor or the back glass of the lens. Vacuum cleaner? Uggh!
