What to know before buying

Listing details to confirm

The listing describes the filter as magnetic and says a magnetic adapter ring is included, but also presents its size as a 67mm thread filter. Confirm the mounting arrangement and compatibility with your lens before buying. The detailed specifications call the body metal, while the feature copy specifies tough magnalium. Water resistance is listed, but no protection rating or use conditions are given. The listing also claims a protective travel case and lifetime backing without clarifying the coverage terms.
