The Haida M10 system is a new handle design that allows quick and easy installation of drop-in filters specially dedicated to this system as well as standard rectangular filters with sizes 100x100mm and 100x150mm. An additional advantage of the new mounting system is the possibility of combining drop-in filters with a standard one. This makes it possible, for example, to combine a full ND drop-in filter with a rectangular ND filter (to generate more extreme densities), while using only the first filter slot (optionally up to 4 filters simultaneously). Especially in the case of wide-angle focal lengths, which are so popular in landscape photography, this possibility is a considerable advantage in terms of vulnerability to vignetting.
