I do not have a 77mm lens any longer. This sale is for 9 items for my old 77mm lenses. The most expensive filter, the circular polarizing filter hasn’t been used. The clear filters are popular to put on a lens to protect it. When you have several thousands of dollars into a lens, it is a good idea to protect the glass. Then there is a case for the filters to keep the filters safe when hiking or traveling. Most of this stuff is brand new. I did use one of the rubber hoods and the $79.99 UV filter to protect a lens. That filter has a small scratch on it but it didn't affect my shots. The other stuff is still in the packaging and has never been opened.
