eBay lens purchase with fungus not mentioned in description - return?

[an1uk]

Bought this lens on eBay. I think the winning bid would be extremely good if it didn't have these issues, and pictures don't seem to be affected.

It appears to be fungus growth on the rear elements, and maybe fungus/separation on elements to the front.

Absolutely…
unless the price was so good that you
could still be happy with absorbing the
fee of the repair.

Yes, return it.

You have every right to if it was never mentioned in the original description. PITA, but it'll only eat away at you if you don't return it.
