Hi Sherwin, as was said, stop worrying. Every lens flares, EVERY ONE,
"ghostless" coating or not, if there is enough difference between the
non-image light and image light. Try shooting into a 500W spotlight in
black room, and you will have flare. Certain sun (after rain, when air
is clear of dust, low on horizont, the sun is stronger than a 500W
spot IMO) is a always-flare. And interestingly, veiling flare is
sometimes more produced by sun not in frame but hitting the elements
at an angle. The more to center of frame, the less flare and vice
versa.

About worn coating - I have coated lenses from early decades of lens
coating, and they are not worn in any way even after decades of heavy
use. Only the very early pre-war prototype coating was much prone to
wear, or early postwar. So I think it was just a bad flare situation.

OTOH, you would have to be REALLY unlucky to have a LTD lens with
coating error - I assume they must pass pretty rigorous tests, as they
are, after all, labeled Limited, in small volume that permits good
testing.

(BTW, all lenses flare. Even late SMC Pentax F50/1.4 flares. Least
flarey is a simple triplet design //well, even less is achromat, than
singlet <g>//)
