Q: 7. 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: 8. Is the description backwards? This looks like it allows one to use a 72mm filter on a 67mm lens. Why would you use a filter that is smaller than the lens?

A: The description is correct; a step-down ring allows you to use smaller filters on larger-diameter lenses. There are a few reasons as to why, for example, to save on the cost of buying filters again if you already own a lot of them in the smaller size. Also, if the lenses have a very narrow field-of-view, the visible vignette might not be significant and not influence the photo that much.

Q: 9. The two answers to the third question say the opposite. Can I use this step-down adaptor to put an 82 VND filter on a 95 lens?

A: Yes, the Cavision 95mm to 82mm Step-Down Adapter Ring for Wide Angle Attachments will allow you to mount an 82mm filter on a lens with a 95mm filter thread.

Q: 10. 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.
