I'm sure this can be tightened and corrected but I'm wondering if it's the kind of thing I might be able to do myself. >> Good question because one of my lenses is doing that as well. I have a Tokina 80-400 and it slides out, too. I would also be interested in hearing from people about this. Thanks!
