I take your thoughts very seriously, Steve. Over the years you have demonstrated care and solid knowledge about our equipment.
What keeps nagging me is that this really seems to be a mechanical issue. I just noticed that when the 150 is at the marker the extendable portion of the lens is still about a millimeter from the end. When I turn the zoom ring to the hard stop it come in that distance and stops. There is no play. Nothing is loose. It just seems that the hard stop for the short end of the lens is not aligned with the marker so that the lens is confused when it tries to report the focal length. I just took a couple of test pictures, one at the hard stop which reports 320 and anther at the detent which reports 150. They are both focused sharply and seems to cover the same area (handheld).
In any case I appreciate your thoughts. The seller is willing to take the lens back but I hate to do that unless I am sure there is a potentially serious problem. Right now all it is is an incorrect focal length at the hard stop.
