Hello,
I unmounted my Tamron 70-300mm from my Nikon D5100 DSLR to put on my 16-85mm (which I purchased used from cameraworld.co.uk a little over a year ago) and it appears broken. I do not know how this has happened, I always take good care of my gear and this has not been dropped. The two videos below show exactly what problem I have with this lens. Please help! When trying to autofocus, it just scrolls through the focal lengths. On manual focus, I cannot pass 30mm. When I shake the lens a bit, it rattles.
