Singh-Ray Variable Neutral Density Filter - 77mm Thin-Frame
- Product Details
Notes: The design of the Vari-ND Filter may introduce irregularities when used with very wide angle lenses, especially on full-frame cameras
This adjustable neutral density filter lets you adjust the Neutral Density affect by simply spinning the end of the filter, similar to how a circular polarizer operates. It gives you control over 8 stops of light.
These filters are very popular for sunsets, where you need to keep the shutter open long enough to expose the foreground without overexposing the background.
