I remember the lens, but don't remember the chip, Brian.
In my experience, the bigger the chip and the shorter the focal length, the
greater the problem - I had an 18-28 zoom with a 1/8 inch (3mm) chip which
was clearly visible in images at the 18mm setting. And once you knew where
to look, it could be found in images at the 28mm setting.
But we are not talking about cleaning marks, which I do agree are not likely
to be of practical impact if they don't form an overall "mist".

The importance of such marks can be over-estimated, as far as I know. I
believe the seller's notes on this were probably fair comment.
How many of you remember the 24mm Zuiko shift lens grafted onto a 6x6 camera
body, that hit eVilBay? That lens had a large chip on one one side, fixed
with a dab of silicone sealant as far I could tell. Made NO apparent
difference, to judge by the large test image posted..
I have read other reports that chips etc especially on the front element
make little or no difference (unless hit by direct sunlight ! )
