The Tiffen 40.5mm Digital HT ND 1.2 Filter is a solid neutral density filter providing a 4-stop exposure. This 1.2 density creates 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 Digital HT coating is a high-transmission multi-coating that surpasses military specifications for hardness and durability. This optical purity combined with high scratch resistance results in an easy-to-clean filter with superb imaging quality. This filter also features low-profile titanium filter rings for increased strength and vignetting reduction.
