The more layers of MRC on a lens filter, the better the protection against scratches, moisture, and oil.

MRC stands for Multi-Resistant Coating and it’s a treatment that protects your filter against scratches and other particles that can affect the filter glass and your image quality. The scratch-resistant, water, and dirt repellent MRC layers make it easier to clean the glass surface and helps to reduce reflection, prevents ghosting and improve the overall image quality.
