The JJC F-NDV58 Variable ND Filter is a neutral density filter with adjustable light reduction from ND2 to ND400, allowing for precise exposure control of 1 to 9 stops. This 58 mm diameter filter maintains original color fidelity and enables photographers to control the amount of light by simply rotating the filter ring. Made from multi-coated optical glass, the filter minimizes reflections and light halos while protecting the lens elements. The variable density range makes it suitable for various lighting conditions, from bright daylight to controlled studio environments. Ideal for achieving motion blur effects in waterfalls, rivers, or moving subjects, the filter also allows for wider apertures in bright conditions for shallow depth of field. Compatible with all lenses with a 58 mm thread, the filter comes with a protective storage case. The neutral density technology ensures that color accuracy remains unchanged across the density range, making it suitable for both photography and videography where precise exposure control is required without compromising white balance or color reproduction.
