;-) I haven't used this example of the 16-50 to really say one way or another whether it might be subtley defective ... I simply prefer to use prime lenses most of the time anyway, in this focal length range. It's one of the lenses I have for 'evaluation', so I suppose I really should examine it a bit more critically.
The shooting I've done with it, however, has all looked pretty good. I just went through 300 some exposures made with it at a wide variety of focal length, distance and scene types: I see no signs of any focusing or sharpness issues, other than those caused by my own sloppiness in using it.
