Product Highlights
  • 3-Stop Exposure Reduction
  • Greater Control Over Exposure Settings
  • 4mm-Thick Glass Construction

The Cavision 4 x 4" Neutral Density 0.9 Filter is a solid neutral density filter providing a 3 stop reduction in exposure. This 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter measures 4 x 4" / 101.6 x 101.6mm and is constructed from 4mm-thick glass.

          Comments about Cavision 4 x 4" Neutral Density 0.9 Filter:

          I prefer to use screw-on B&W ND filters when possible but sometimes I need ND and split ND filters in combination. My split ND's are all 4x6" and I use the Lee filter holder for these so I added this square ND to use with that system. To avoid light leakage I place this filter closest to the lens. Due to the protective plastic rim, this Cavision filter is 4mm thick so you need replace the stock Lee filter spacer with a thicker 4mm one.

          This arrangement works fairly well although multiple filters in front of a lens can be problematic in some lighting conditions. Careful lens shading takes care of this in most cases.

          So far the Cavision ND filter has not degraded image quality in any visible way but since I only use it in combination with split ND filters, problems specific to this filter would be hard to spot. In the end, it solves a problem I encounter infrequently and it does not cause any obvious degradation.

            Comments about Cavision 4 x 4" Neutral Density 0.9 Filter:

            Glass filter has a boarder (coating, resin? perhaps) around it. This boarder/frame increases the width past that of the glass filter and creates a snug fit in the filter holder. I am using this filter with a formatt hitech 100mm 4x4 filter holder. The filter fits snugly and feels secure in the filter holder. I have only used it a few times, but images are good and I have not noticed any color shifting from filter.
