Panasonic 37mm 0.9 ND Filter

Panasonic 37mm 0.9 ND Filter is a solid neutral density filter providing an exposure reduction of about 3 stops. 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
