This 1- to 3-stop, 52mm Hoya Graduated ND Filter helps to specifically darken skies and other bright areas of the image. The filter has a 3-stop density at one edge and evenly tapers to a 1-stop density at the opposite edge, with a smooth gradation throughout the middle of the filter plane. The design of this filter incorporates a rotating mount to allow precise positioning of the density over a selected area of the scene for greater control in darkening the brightest areas of an image. A neutral density filter does not affect the overall coloration of an image and helps to reduce the amount of light entering the camera lens in order to enable the use of wider aperture settings or longer shutter speeds.

This filter is constructed from one wedge layer of clear optical glass that is matched and bonded to a second layer of neutral density filter glass for a smooth, even density transition that maintains high image quality. It is set within a durable rotating aluminum filter ring.

Q: 1. how can I tell what size screw on sense I need for my specific size lenses?

A: The thread pitches are all the same. All you need to do is make sure the diameter of the lens (usually marked on the lens with a number and a circle with a line across it) is the the same is the size filter that you want to fit on it.

Q: 4. Is this recommended for digital cameras?

A: The Hoya 72mm Neutral Density (ND) 0.3 Hoya Multi-Coated (HMC) Glass Filter is recommended for both digital and film cameras. Hoya's Pro Digital line of filters are slimmer but still have threading on both sides of the filter. Ultra-thin filter frames help to avoid vignetting on super wide angle lenses while the front threads mean they will also hold a lens cap. HMC filters feature a 3 layer multi-coating while their Pro Digital line's multi-coating is optimized for use with digital sensors.
