Sony 16-70 f4 Faulty or ??

I purchased this lens second hand last week from a main UK dealer.  The lens was described as mint and indeed it is.  Took the lens for a test run on Friday  shooting in raw on an A6500.  After converting the files I was alarmed and dismayed by how bad the edges are.  I don't mean extreme corners but for me quite early on the edges of the frame.  In every shot there is an almost immediate drop in sharpness in from the edges.  This is seen at all edges as well as the corners and isn't far off from about a third of the frame counting both sides.  You could almost draw a line with one side being acceptably sharp and the other soft.  All shots were taken at f5.6, 6.7 or 8.

Anyone else using this lens and experiencing similar behaviour?

Thanks in advance.
