What to know before buying
Listing details to confirm
The listing is internally inconsistent: it describes the filter as MRC Nano and the title also says MRC Nano, but the coating field says “No Coating”. The title and feature list say 52mm, while another size field says “52 Millimeters”. A separate screen-size field says “2.05 Inches”, which is not explained for a camera filter. Confirm the intended coating and size details for the selected listing before purchase.
