What to know before buying

Listing details to confirm

The 105mm filter thread is the key fit specification. Confirm that the lens accepts a 105mm filter before buying. The listing also labels 105 Millimeters as a screen size, which does not apply to a lens filter, and describes the rim as magnalium while listing glass as the material. These details are inconsistent, so treat the screen-size entry and rim-material claim as unconfirmed. The manufacturer claims a lifetime backing, but the supplied information does not explain its terms.

Who is it for?
