FotodioX WonderPana FreeArc Core Filter Holder and Bracket with ND 1000 and Soft-Edge Graduated ND 0.6 Filters Kit for Sony 12-24mm Lens

Offering increased control over exposures, the Pro 145mm Ultra Slim ND 3.0 Filter from Fotodiox is a neutral density filter used to darken the entire image, thereby allowing you to increase exposure times or work with a wider aperture setting than usually required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. The ND 3.0 density of this filter requires a 10-stop increase in exposure to achieve a normal exposure.

The filter is made from optical glass, which has been multi-coated to maintain image quality when working in strong lighting conditions. The glass is set in a 3mm-thick anodized aluminum ring that is lightweight, durable, and slim to help prevent vignetting when used with wide-angle lenses.

The FotodioX 6.6 x 8.5" Soft-Edge Graduated Neutral Density 0.6 Filter is a filter designed for use with the WonderPana 66 and FreeArc filter holder systems. It helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. Neutral density filters do not affect the coloration of the image and this filter provides up to a 2-stop reduction in light from entering a lens.

This filter is made of durable, optical resin (CR39) and measures 4mm thick. A carrying pouch is also included with the filter.
