The FH100M2 Filter Holder from Benro is an updated version of their original FH100 holder. Like the original FH100 holder, it is designed to hold both square and circular filters, with the ability to freely rotate an attached 82mm CPL filter after installation. It will hold up to 3 square filters, and ultra-thin 82mm CPL simultaneously, without creating vignetting on lenses as wide as 16mm.
It features a new compact design that helps to reduce light leaks, smoother CPL rotation, and adjustments that help to prevent filters from accidentally sliding out of the holder. A gear has also been added that allows the filter to move up and down for precise adjustment, and the structure of the lens ring is simplified, making it compatible with additional lenses. Lastly, the holder is easier to install and remove, which is particularly convenient when working with high ND value filters.
