NEW OLD STOCK  
 
58mm Rodenstock Vario ND Extended Neutral density filter for reducing brightness, extending exposure time and intentionally reducing the depth of field.

Especially suitable as a fader for video shots with DSLR, mirrorless camera or camcorder, if with open aperture (shallow depth of field) a specified shutter speed/frames per second rate (fps) is required.
 
Filter reduces light by 1.2 - 6 stops allowing for longer exposures or wide open apertures to be used in bright conditions.  

Premium optical glass  with perfect surface quality. Highly scratch-resistant. Neutral-tint reducing colour cast normally associated with ND filters.
