Kase Rear Lens ND Filter Kit for Sigma 14mm

This Kase Rear Lens ND Filter Kit contains three filters that are each compatible with the built-in rear filter slot of a Sigma 14mm. Each filter can be used individually to create a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, 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.

The kit's ND 0.9 filter, ND 1.8 filter, and ND 3.0 filter provide a respective 3, 6, and 10-stop exposure reduction. These filters are constructed from tempered optical glass for shock resistance. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes multiple layers of anti-reflection coatings. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

A plastic case is included for storage and transport.
