ZERO Coating

The Zuiko Extra-low Reflection Optical, or ZERO, coating features a thin-coating technology works to produce a clear and high contrast image due to reduced reflection on its surface. The coating also benefits from the vacuum deposition method to prevent scratches to ensure stable low-reflective performance.

Construction

The optical glass filter is set within a one-piece matte black anodized aluminium ring, which lessens the likelihood of vignetting if used on a wide-angle lens. There is also a black coating on the glass edge to reduce reflections. Knurling can be found on the frame that makes the filter easy to attach and remove. Additionally, the ring features front threads for attaching additional filters or lens caps.
