I just purchased a used camera. It is a Nikon D100 which came with a Tamron 200-400 mm lens...
I have attached the long lens, and of course I want to check it out right away, but the lens will not turn to allow me to zoom in or out. ie; it seems to be locked at 200 mm... I can't find a button anywhere on the camera that will unlock the lens.
Thank you in advance
