Features and Functions: Rotating filter ring with scale indicating max. through min. settingsProvides 1.5 - 9 stop exposure reduction, equal to filter factor NDX3 - NDX400Enables slow shutter speeds to be usedAllows greater control over depth of fieldDoes not affect colour balance or detail Description: The Hoya 58mm Variable Density Filter minimizes the vignette effect often experienced when shooting with wide-angle lenses. In this updated version, Hoya improved the frame of the predecessor Variable Density filter, making it thinner for better handling of vignetting. The filter features a dedicated knob for precision rotation between an adjustable neutral density range of ND3 to ND400 (1.5 to 9 stops). It also allows you to attach an optional lens cap. It supports lens caps that are one size larger than the filter size.
