Hoya PROND EX 64 49mm grey filter

Hoya PROND EX 64 49mm

A grey filter (ND) is used to reduce the amount of light entering the cell. The filter is very useful when shooting in bright daylight when long shutter speeds are required. For example, when you want to capture the movement of water in a soft way, a shutter speed of several seconds is preferable. Also when shooting video, the ND filter often comes in handy, as the shutter speed is often between 1/50 and 1/200 and the aperture is at its widest.

The Hoya PROND EX 64 filter reduces the amount of light passing through the lens by as much as six aperture values. In other words, in a lighting situation where you would have to set a shutter speed of 1/1000 without the filter, the filter allows you to set a shutter speed of 1/15 of a second. The EX 64 is therefore suitable for bright lighting conditions that require significant light reduction.

Hoya's PROND EX branded filters combine precise optical glass with a lightweight aluminium frame. The frame includes threads on both sides, meaning that another filter can be attached to the front of the filter, such as a Rotary polarising filter.

. Thanks to the ACCU-ND technology of the filter, the image does not suffer from the colour distortion that can occur with some lower quality filters. In practice, ACCU-ND technology provides an equal amount of light reduction at both visible and infrared wavelengths.

Key features:

• Filters light by up to ten aperture values
