Close-Up Filter A close-up filter, also known as a macro filter or close-up lens, is an optical accessory used to enable closer focusing distances and magnification capabilities with standard camera lenses. Close-up filters are typically screw-on attachments that mount onto the front of a camera lens, effectively decreasing the minimum focusing distance and allowing photographers to capture detailed close-up images of small subjects such as flowers, insects, or jewelry.
Close-up filters come in different diopter strengths, which determine the level of magnification and close-focusing ability they provide. They offer a cost-effective alternative to dedicated macro lenses and are popular among hobbyist photographers and enthusiasts interested in exploring macro photography without investing in specialized equipment. |
