RAYDAWN UV Filter 43mm
Ray Dawn's high quality matte black (to prevent reflections) anodized brass rings reduce binding/cross threading to ensure optimal alignment.
Ray Dawn filter rings come in various thicknesses. The standard thickness ring is by far the most-commonly chosen, but a slim ring is available for reduced vignetting on ultra wide angle lenses. For most wide angle lenses (in general, wider than 40mm), with and without standard UV filter test results are available in the vignetting tool (look for the second-to-last focal length option). This tool allows comparison to determine if the standard filter depth causes light to be blocked from reaching the corners of the imaging sensor.
