This 4 x 5.65" SmallRig Cine ND Filter 4x5.65 7-Stopfrom SmallRig Cine ND Filter 4x5.65 7-Stopis an ND2.1 neutral density filter that produces a 7 f-stop exposure reduction, making it possible to reduce shutter speed for added blur when shooting still images, or for finer control over frame rate when shooting video. In addition, shooting at a wider aperture to reduce depth of field helps isolate the image subject from the background. This filter is compatible with any 4 x 5.65" matte box or filter holder that has a filter slot for 4mm-thick filters.

Made with high-clarity, high-transmission B270 optical glass, this filter is precisely ground and polished for use with lenses of various focal lengths without compromising image sharpness. The filter is coated on both sides with multilayer nano-coating to reduce lens flare and optimize light transmission. The coatings are also mildewproof and water resistant, toughened to prevent stains, and easy to clean, making the filter ideal for use in harsh environments.

Q: 1. will this work in an arri lmb25 4x5.65 tray?

Q: 7. Is the 1-1/4 stop fabric thick enough to beam a small source light into it, and not have a hotspot? I'd like to use an Astra 6X at around 4ft away to result in a large even light source

A: That should be a good distance to get a even light onto the diffuser and not have a hotspot.

Q: 8. Are the filters IRND?
