Those figures do look kind of interesting. I noticed it was the ATX
model, which I thought was the top of the line for tokina. But if it is
that good, why did it go so low? Maybe because the seller listed it as a
filter primarily? Anyways, it is still in the mail, and remember the
condition of the lens was not described, so it is a bit of a gamble. But
for the price I won't worry too much if it is full of fungus and has to
go in the garbage. Wayne
