The V7 Alpha 100mm Aluminum Filter Holder from NiSi is designed to use up to three 100mm wide filters with a thickness of 2mm. It includes an 82mm adapter ring to allow the holder to connect to any 82mm standard filter thread lens. This holder can be combined with NiSi's separately available V7 adapter rings to allow the use of standard filter thread sizes ranging from 49 to 77mm. The included 82mm adapter ring is also compatible with the V6 adapter rings from 49 to 77mm.

Additionally, this holder features a left-to-right pressed clip design that allows filters to be smoothly inserted and removed. The holder can rotate 360� to allow graduated neutral density filters to be rotated for perfect placement with a horizon and light source. Made from aviation-grade aluminum, this V7 Alpha filter holder offers a locking system for fixing the filter position and avoids vignetting on the ultrawide-angle lens even at 16mm on a full-frame camera.
