The K&F Concept equipped lens filter kit includes:

• UV Filter
• CPL Polarizer Filter
• Neutral Density Filter (ND4)
• Filter Case
• Soft Lens Cleaning Cloth

Imported Optical Glass: All filters are made of imported Japanese optical glass with a blue coating, high anti-reflectivity to ensure the true color rendition of the image and quality. The CNC frame design increases friction for easy installation and removal of the filter.

With lens cleaning cloth and filter case: The optical microfiber cleaning cloth has a fine texture, is soft and lint-free, can be washed and reused - ideal for cleaning dust from lenses and cameras. The filter case can hold 3 filters and is easy to carry.

ND4: 2 stops with 25% transmission, made from blue-coated imported glass, very thin telephoto lens and wide-angle lens, avoiding the darkening effect.

These K&F Concept filters are compatible with all 52mm lenses.
