This 72mm Neewer Variable ND Filter 72mm 1.5-10 Stopfrom Neewer Variable ND Filter 72mm 1.5-10 Stopprovides an increase in neutral density through a range from 1.5 to 10 stops. Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background and increasing bokeh.

The filter is made from optical glass that features multicoating for reduced lens glare, and resistance coating that resists water, oil, dust, fingerprints, and scratches, making it ideal for use in harsh environments, and also easy to clean.

Note: This 72mm filter requires a larger 77mm lens cap, not included.

Q: 1. Would this work with my old sigma 10-20mm 4-5.6 dc hsm and the new EOS R7? I only see the Sigma 10-20 3.5, on the compatibility list
