Marumi Gray Variable Filter DHG ND2-ND400 72 mm

The Marumi Filter DHG ND2-ND400 is a variable neutral density filter with a diameter of 72 mm. Neutral density filters come in various strengths, such as ND2 (1 stop), ND4 (2 stops), ND8 (3 stops), and so on. Marumi's variable neutral density filters consist of two polarizing filters that can rotate over each other, allowing you to adjust the amount of light attenuation. A single variable neutral density filter can therefore replace a series of fixed neutral density filters, making it more practical to use. By turning the ring, you reduce the light from ND2 to ND400 (1 to 8 stops).

• Variable gray filter with a diameter of 72 mm
• Consists of two polarizing filters that can rotate over each other
• Controls the degree of light attenuation
• Replaces a range of fixed ND filters
• Light reduction from ND2 to ND400 (1 to 8 stops)

A gray filter is used as a filter for example to:

• Extend shutter speed to capture movement such as flowing water
• To reduce the depth of field of a photo
• Using an aperture further away from the diffraction limit, resulting in a sharper photo
