The K&F Concept VND2-400 is a filter kit with a 49mm thread size. This type of filter is known as a Variable Neutral Density (VND) filter, offering a variable density range from ND2 to ND400. This allows photographers to adjust the amount of light entering the lens, providing flexibility in various lighting conditions.
The filter kit is compatible with a range of DSLR cameras, including Canon models such as 7D, 700D, 600D, 70D, 60D, 650D, and 550D, as well as Nikon models like D7100, D80, D90, D7000, D5200, D3200, and D5300.
The filters in this kit are made with professional optical glasses rather than optical resin. Optical glass is often preferred for its clarity and optical quality, ensuring that the filters do not compromise image sharpness.
The kit includes a lens cleaning cloth made of professional microfiber, which is sourced from Japanese raw material. This microfiber cloth is soft and designed for cleaning lenses, filters, glasses, and other optical surfaces. It provides an effective and gentle cleaning solution.
