Q: 9. I'll be using this on my 85mm Tessar ZM which has 43mm filter thread. All of my filters (CPL and ND) have 39mm filter thread. Will my 85mm Lens vignette by using this item?

A: Anytime you use a step-down ring to use a smaller filter on the front of a lens with a larger filter diameter, you run the risk of obtaining some vignetting. Unfortunately, we have no way to test or guarantee which lens/focal length combinations. While vignetting would normally be more noticeable with wide angle lenses compared to telephoto lenses, I cannot guarantee you will not get vignetting. The best I can state would be to purchase the item and see if it works for your needs, and if it does not, you would have 30 days to return the item for an exchange or refund via our 30-Day Return Policy on this item.
