◯ This is a FUJIFILM teleconversion lens (silver). It's for the FinePix 4900Z, 6900Z, S602, S304, and S5000, but it should be possible to attach it to other manufacturers' lenses if the lens diameter is compatible. ◯ Similar to filters, it attaches by screwing it onto the end of the lens. The diameter is 55mm. ◯ I couldn't find any mold, etc., upon inspection. The lens condition is good. ◯ This is an auction for the lens body only.
