H&Y Filters K-Series Neutral Density Filter with Quick Release Magnetic Filter Frame (100 x 100mm, 4-Stop)

100 x 100mm K-Series neutral density filters are constructed from Gorilla glass for enhanced scratch resistance, increased clarity, and color fidelity. Each side of this filter includes eight layers of anti-reflection coating to prevent internal ghosting and reflections as well as an anti-smear nano coating for an improved beading effect when in contact with water or oil for greater cleaning efficiency.

The 100 x 100mm K-Series Neutral Density 1.2 Filter is pre-installed with an 100 x 100mm H&Y Filters Quick Release Magnetic Filter Frame for use with an H&Y Filters 100mm K-Series Filter Holder. When combined with a 100mm K-Series Filter Holder that is configured with a pair of magnetic filter slots, filters each with a Quick Release Magnetic Filter Frame can be magnetically stacked in front of a camera lens instead of inserted only within a specific number of filter holder slots, allowing the user to determine the number of filters to be applied, all of which can be quickly installed, repositioned, or switched with a different filter needed for other subjects or changing lighting conditions.

While in use, front-facing center finder rulers on the side sections of this Quick Release Magnetic Filter Frame help enable precise positioning of the 100 x 100mm neutral density filter, relative to another filter it is stacked on. The Quick Release Magnetic Filter Frame also serves to reinforce the edges of the 100 x 100mm neutral density filter, enhancing that filter's rigidity and promoting sharp results by helping to ensure that the filter remains flat. A filter pouch for storage and transport, as well as a microfiber cleaning cloth for filter maintenance, are also provided.
