LEE Filters 100mm Adapter Ring for Nikon PC 19mm f/4E ED Tilt-Shift Lens

Made specifically for the Nikon PC 19mm f/4E ED 19mm tilt-shift lens, this Adapter Ring from LEE Filters allows you to connect a filter holder and use 100mm square filters with your lens for a wide variety of effects. It does not attach via threads due to the bulging front element of the lens, opting instead for a compressor ring that goes around the barrel like a collar. You can simply attach it and leave it on, then connect a separately available holder whenever you need to use filters. Note that the adapter ring sits quite close to the front element, and therefore does not allow for full lens movement without vignetting.
