I don't know about the threading of the lens, nor have I used this lens. I did use a different Olympus lens (not a TCON-17) before with my Fuji S7000. I think it was 1.5X optical zoom. It was ok. Go to:
for a different person's opinion.
It's a good price. I feel better about that lens than those cheap ones on Ebay.
If you end up getting it, let me know how it turns out.
