Benro Master Series 170mm Filter Holder

Compatible with filters with thicknesses up to 2mm, theMaster Series 170mm Filter HolderfromBenroallows you to use several filters simultaneously for stacking their effects. It is designed to fit most ultra-wide lenses without filter threads, and can be used with models that have an angle of view up to 110 without any problems. Alternatively, you can mount the holder normally with the included 95mm mounting ring and 95-77m step-down ring, making it compatible with lenses that have either of those front thread sizes.
