Q: 5. 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.
