Q: 3. Is this only a step up ring or one can use 95mm Kase ND filter and snap it in directly to this step up?

A: To use the Kase 95mm magnetic filters on a lens that uses 72mm filters, the only step up ring adapter is the Kase 72-95mm Magnetic Step-Up Adapter Ring for Wolverine Magnetic Filters BH #KAKWMSP7295 • MFR #KW-MSP-7295

Q: 4. how much vignetting would occur on a 82mm filter using a step up ring? unfortunately my sigma 70-200 has 82mm front threads. It wouldn't kill me if I had to crop in a bit to eliminate the vignette.

A: The Sigma 70-200mm f/2.8 referenced has a 82mm front threading and you would need a step down ring from 82mm to 77mm to mount the NiSi 77mm Close-Up NC Lens Kit II with 67 and 72mm Step-Up Rings. It is possible that this will vignette slightly.

Q: 5. Will this adapter work with the 67ii lenses as well? Would this work with the new pentax K-3?
