Filtras Rollei, Neutraliai pilkas, 70 mm

Prekės aprašymas anglų kalba:

The Rollei Pro Square ND Filter is a rectangular-shaped, professional, neutral-density filter. The abbreviation ND stands for Neutral Density, which refers to light density. In colloquial speech, we also talk about “swallowing light”, since the ND filter also reduces the amount of incoming light. This produces a uniform darkening, which also explains the alternative name, “grey filter”.
