Unfortunately, only 100 mm wide filters made of glass or plastic with a thickness of 2 mm fit in the holder. I use ND filters 100x100mm and graduated filters 100x150mm.

This is possible if you don't have a suitable adapter ring. However, when reducing larger lens diameters, caution is required because of possible vignetting.

As long as you insert the filters upright into the filter holder and they are no thicker than 2 mm, they will fit. They just look over at the ends, but that doesn't bother me.
