Kase Round Screw-In ND Filter (150mm, 6-Stop)

This 150mm Round Screw-In ND Filter from Kase reduces exposure across and entire image by 6 stops. The reduced exposure makes it possible to shoot with longer shutter speeds to enhance motion blur and the sense of motion in an image. It also makes it possible to shoot with a wider lens aperture for shallower depth of field.

This filter is made of optical glass with nano-coating to reduce potential lens flare, and optimize light transmission and color accuracy. It also allows water and oil to bead up for easy cleaning.
