Capture dreamy images with the Black Diffusion Cinematic Effect Filter from Neewer, compatible with lenses with 40.5mm filter threads. This 1/4 density filter softens hard edges and provides a smoothing effect by reducing contrast and the overall value of highlights. Constructed with optical glass and an aluminum frame, it has 30 layers of nano multicoating for an anti-oil, anti-scratch, and water-repellent surface that can keep your lens safe. In addition, it is slim enough at 3.3mm thickness to prevent vignetting.
