Walimex ND Fader - 55 mm

The ND fader by Walimex ensures an even dim-out of the picture. It reduces the amount of light and by doing that also extends the shutter speed by +2 to +8 f-stops. The fader unites several ND filters, and as adjusting is possible steplessly, it allows an even finer tuning than one filter would allow. It makes longer exposure times possible, giving you a wiping or flowing effect in long exposure shots. With it, e.g., flowing water looks very soft or like flowing fog.
