Q: 9. Does this filter fit a 18-55mm lens?

A: It would depend on the specific brand/model of the lens in question, as different 18-55mm lenses use different filter thread sizes. I would check the filter thread size on the front of your lens, or possibly on the inside of the lens cap, to verify the size of your lens' filter threads. If your lens uses 55mm filters, then yes, the Tiffen 55mm UV Protector Filter should work for your needs. If you are not sure of your lens' filter thread size, I would recommend e-mailing askbh@a href= http://bhphotovideo.com target= _blank bhphotovideo.com/a with the full name of your lens (or all text written on the lens) so we may try to verify your lens' filter thread size.
