Thank you for viewing. This is a Nisi variable ND filter, 77mm. I used it once or twice, and haven't used it since, so I'm putting it up for sale. It's almost like new. The contents are as follows: Nisi filter case ND-VARIO 1-5STOP 77mm Step-up ring 67mm → 72mm Step-up ring 49mm → 67mm The step-up rings are included as a bonus. Please understand that this is a used item, and only purchase if you are okay with that. - Brand: NISI - Accessories: Case - Filter Type: ND Filter
