This NiSi 180mm Filter Holder is designed to allow for the convenient use of 180mm wide, 2mm thick filters with a Canon EF 11-24mm f/4L USM lens without vignetting.

Use of the filter holder is easily accomplished by first sliding it over a Canon EF 11-24mm f/4L USM lens's integrated hood. The filter holder's screw-on locking pin helps to provide a reliable connection while the holder can be rotated 360°, permitting the use of graduated neutral density and other filters that are enhanced by varied positioning.
