A square filter holder clamps to the front of a lens through an adapter ring and lets you slide in square or rectangular filters, such as graduated neutral density filters for sunrise skies or strong ND filters for long exposures. The holder width must match the filters you plan to use.
The six systems below cover 75mm, 100mm and 150mm filter widths. Details come from each product’s listing page. We have not used these holders ourselves. Build and compatibility claims are the makers’ own, so check your lens thread size before ordering.
