K&F Concept 100x100mm Square ND1000 Filter Kit

The K&F Concept 100x100 mm ND1000 is a square filter kit designed for long exposure photography and intense light control outdoors. By combining a 10-stop ND filter with a metal filter holder and eight adapter rings, it allows you to work with various thread diameters without having to purchase a dedicated filter for each lens.

The optical piece is built in AGC glass with 28 layers and a design aimed at reducing reflections, facilitating cleaning and better resisting field use. The included system covers 49, 52, 58, 62, 67, 72, 77 and 82mmlenses, and the square 100 x 100mm format is useful for landscape, architecture and scenes with moving water or clouds.

It is an especially practical option for those who want to enter a square filter system with a contained investment. It also makes sense for photographers who switch between multiple optics and need a single strong ND for long exposures, video with slower shutters, or creative daylight shooting.
