I've used this with my H4D50 with both a 100mm and 28mm and the results are excellent. It is in mint(-) condition, it has a few pin point marks on the black frame but the glass is perfect. It will also work on the 35, 50, and 80mm lenses. I don't know but it might also work on the XD1 with the HC lens adapter (?).
Price = $3150 net to me.
Let me know if you have any questions or need more photos.
Thanks,
Gale
