This M15 Filter Holder Kit is designed for use with a Sony FE 12-24mm f/2.8 GM lens. It allows for the convenient use of up to two separately available 150mm wide, 2mm thick filters along with a separately available Haida Magnetic Filter for the Haida M15 Filter Holder. Mounted within a nonthreaded aluminum alloy ring, a Haida Magnetic Filter for the Haida M15 Filter Holder is made specifically to fit between the included Haida M15 Filter Holder and an adapter ring for the filter holder. For filters such as a Haida Magnetic Circular Polarizer, the filter holder's external dial integrates with the filter ring, allowing for the independent rotation and adjustment of those filter types.

Preinstalled with one pair of plastic filter slots, the aluminum alloy filter holder is initially configured to accommodate one rectangular filter. Use of the Haida M15 Filter Holder is easily accomplished by placing the kit's adapter ring over the integrated hood of a Sony FE 12-24mm f/2.8 GM lens, followed by an optional Haida Magnetic Filter for the Haida M15 Filter Holder. After being fitted onto an adapter ring, the filter holder's pull-and-release locking knob helps provide a reliable yet adjustable connection that allows the holder to rotate 360°, benefitting the use of rectangular graduated neutral density or other filters enhanced by varied positioning.
