The Urth 95mm ND8 128 (3 7 Stop) Variable ND Lens Filter is a high-quality screw filter designed specifically for photographers and videographers who seek precise control over the exposure of their shots. With a diameter of 95 millimeters, this filter is suitable for a variety of lenses and allows for the reduction of the amount of light hitting the sensor. The ND filter (Neutral Density) offers a variable density that enables exposure reduction of up to 7 stops. This is particularly useful in bright environments where overexposure must be avoided. The filter is ideal for long exposures to create motion blur or for use at wide apertures to achieve a shallow depth of field. The construction of the filter ensures high optical clarity and minimizes color distortion, so image quality is not compromised. The Urth ND filter is thus an essential tool for creative photographers and filmmakers looking to expand their artistic possibilities.
