Hi MikeMck; I have had the Sigma 18-250 since 2005 I use it on a Nikon D-90. Never had a problem with this lens. Maybe the one you got was just defective, I love mine.............Mike
Thanks. This was supposed to be a "new revised" lens. I have read other comments from Amazon and several people have had the same problem. I just wondered how many of this site have experienced this.
