I have a used 28mm/f1.8 lens for Canon sitting on my shelf (wrapped up neatly) that I have no use for.

I am asking $300 for it, shipping extra -- that is about the price they are going for on Amazon, used, in good condition.  Mine is in very good condition.  I don't think there's any dust in it, or scratches on the lens.

I will add pictures later.
