Q: 5. I noticed that the individually sold 67-77mm Sensei step-up ring is sold as (and is marked) "Sensei Pro". But, the rings in this kit are not marked with the "Pro" designation. What is the difference being as the single 67-77 "pro" ring costs 50% of what this kit costs??? Thanks!

A: The pro rings are matte black and have knurled edges.

Q: 6. What is the difference between this one and SESDR7767 which is the same brand but doesn’t have “pro” in the name?

A: The Pro has knurled edges for a better grip and corrosion resistant aluminum alloy.

Q: 7. I have a 300-600mm Tamron lens and have a 77mm Cokin Z-Pro Series Filter Holder Adapter Ring. Is this what I could use on my 95mm lens?

A: You cannot. This product is specifically for Wide Angle Attachments. Using a 77mm filter system on a lens with a 95mm thread will be very difficult, there may be vignetting caused by using such a smaller system on a larger one and we do not recommend it.

Q: 8. Any vignetting? I would be using 37mm macro filters on 46mm lenses. Thanks!

A: Regarding the Sensei PRO 46-37mm Aluminum Step-Down Ring, yes, using 37mm on a lens with a 46mm diameter may cause vignetting.

Q: 9. Are there any side effects (vignetting, i think is the term used) when using the smaller 77mm filters on the larger 82mm lens?

A: Hi again Steve, just received your reply. I did not consider going to a full frame camera. Throwing that into the mix especially with a 24-70 lens I think pretty much would cause vignetting. Going from an 82mm down to a 77mm equals about one-quarter inch that would equal a one-eighth inch reduction on each side of the filter's rim. I would expect you'll get a lot of vignetting. One consideration is that the Sensei 82-77 step-down ring is not really expensive and if it caused too much vignetting you're not out a lot of money for the ring itself. I buy that brand, as they work very well and at a low cost. I would say to start saving for 82mm filters; I think you'll fine more vignetting than you'll want to deal with, especially going to a full frame camera and that lens.

Q: 10. Can I use this StepUp on a Fujifilm X30?

A: No; 40.5 is too large to go on the X30. It is frustrating to try to attach anything to these little Fuji lenses. I ended up buying a lot of miscellaneous caps, hoods, step up rings, and filters. I finally gave up and purchased the Fuji hood that came with a clear filter (size not specified but perhaps a 40mm) and a pinch cap. It seemed like an unreasonable price, but it works well. All the other filters and step up rings and caps are part of my estate.
