The Fotodiox 145mm Pro Ultra Slim Neutral Density 1000 Filter is a solid neutral density filter enabling a 10 stop increase in exposure. This 3.0 (ND 1000) 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 overall coloration of the image.
This filter is constructed from multi-coated optical grade organic glass to maintain image quality by minimizing lens flare and surface reflections. It is set within an anodized aluminum slim-profile filter ring to help reduce the likelihood of vignetting when used with wide-angle lenses. It is compatible with WonderPana 145/66 filter holder systems.
