Related Questions and Answers

Q: 1. 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: 2. Is it only magnetic or is it like the Helix ones that also click into place with a small turn?

A: The Freewell V2 Magnetic Hybrid Variable ND with Circular Polarizer Filter (3 to 7-Stop) is magnetic only.

Q: 3. Will this fit the V7 100mm filter holder?

A: Yes, the NiSi 67mm Adapter Ring for Swift System Filters will work with the NiSi 100mm V7 Starter Kit, NiSi 100mm V7 Professional Kit, NiSi 100mm V7 Night Photography Kit and the NiSi 100mm V7 Advance Kit.

Q: 4. What other size lenses does this filter attach to?

A: The Freewell V2 Magnetic Hybrid Variable ND with Circular Polarizer Filter (3 to 7-Stop) comes with 82mm adapter and will mount on lenses that have an 82mm filter thread.

Q: 5. Can you screw in your already existing polarizing filters into this adapter, or do you have to buy the Lee polarizer?

A: This is an adapter ring for use with the Lee filter holder and is not for attaching a filter to it. You need the filter holder and a Lee polarizer.

Q: 6. Will this fit the V7 filter holder?

A: Yes, the NiSi 67mm Adapter Ring for Swift System Filters will work with the NiSi 100mm V7 Starter Kit, NiSi 100mm V7 Professional Kit, NiSi 100mm V7 Night Photography Kit and the NiSi 100mm V7 Advance Kit.

Q: 7. Will this work with a 67mm step up ring?

A: The Freewell V2 Magnetic Hybrid Variable ND with Circular Polarizer Filter (3 to 7-Stop) is compatible with the Freewell 67mm Step-Up Adapter Ring for V2 Magnetic Filters, BH #FRFWV2SU67.

Q: 8. Will this size fit my sigma 10-20mm lens? I just got my 77mm but I find it a bit to big for my lens. Just need help on finding the right size ring adapter.

A: I'm sorry Jeremy, I don't own any sigma lenses, but doesn't the 10-20mm have a 82mm thread?

Q: 9. Hello, will this work on a Canon EF 35mm f1.4 L II USM lens? Thank you

A: The front filter thread for the Canon EF 35mm f1.4 L II USM lens is 72mm so this adapter ring for the lee filters kits will work perfectly!

Q: 10. Does this work for the seven5 system? I bought a standard 72mm to seven5 adapter ring and got severe vignette at 16mm. Does anyone have any solution?

A: Unfortunately, this LEE Filters Adapter Ring - 72mm - for Wide Angle Lenses would not be compatible with the Seven5 filter holder. Im not aware of any 72mm adapter rings for that filter holder that would be specifically made for wide angle lenses. And, as 72mm appears to be the largest adapter ring, there wouldnt be the option to use a larger adapter ring with a step down ring. You might need to look at a different filter holder/system for your lens.
