The Singh-Ray 58mm Thin Mor-Slo Solid Neutral Density 4.5 Filter is an ND filter with a 32,000x filter factor that provides a 15-stop exposure reduction. Its 4.5 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.
This Singh-Ray neutral density filter is constructed from optical glass for clarity as well as color fidelity and features a thin, 4.6mm aluminum-alloy filter ring for durability which also minimizes the potential for vignetting while remaining lightweight.
