The M10-II Filter Holder from Haida attaches to the front of your lens using an optional adapter ring. The M10-II is compatible with the adapter rings of the predecessor M10 filter holder. Attached to your lens, the M10-II supports up to three 100mm wide, 2mm thick rectangular filters and a single M10-II drop-in filter, such as the dedicated M10-II CPL, sold separately.
The second generation of Haida's M10 100mm filter holder, the M10-II is upgraded with a nonslip design that allows for easier handling in most weather conditions. It also has a new locking design for quicker attachment to adapter rings. New filter guides snap into place rather than requiring screws to be used as in the predecessor version. Also, a new locking knob will keep the holder in place after it has been rotated.
