I wonder how someone can link to photo's that aren't their own
shnykies, I've seen great photo's taken with similar glass, however in my opinion there is a quality difference between individual lenses.
If you can ask that person to post some photo's actually taken with that lens.
If he can't it might be a lemon (or he might be a film guy without a scanner)
Although for that price it's worth the risk
I don't see anything wrong with mentioning the eekbay auction here.
It gives members that might also want the lens a chance to bid on it.
They can change the adapter easily enough
