Lee Filters ProGlass 150x150mm IRND 6 Stop 1.8 ND Glass Filter

LEE Filters has launched a brand new range of high-quality neutral-density filters. The ProGlass IRND range was developed in response to a demand from the movie industry for ND filters that could stand up to the rig ours of the film set. Now, the same filters are available to the photographic industry, along with longer-exposure versions that have been made possible thanks to technological advances in coating. Thanks to LEE Filters' complete control over the manufacturing process, ProGlass IRND filters are precisely neutral, with virtually no color shift and extremely accurate stop values. And because they block both infrared and ultraviolet pollution, blacks remain pure and clean, while colors are crisp, punchy and vibrant.

The six, ten and fifteen-stop filters feature a foam seal, which fits snugly to the filter holder to avoid light leaks. These filters should be used in the slot closest to the lens for the most secure fit. While the two, three and four-stop versions do not have a foam seal, they should also be used in the slot closest to the lens. ProGlass IRND filters can be used in conjunction with the likes of neutral density grads and the polarizing filter, for even greater control of the in-camera image.
