This is an OLYMPUS CLA-4 conversion lens adapter for the Olympus CAMEDIA C series digital cameras. It supports 46.5mm to 55mm. It has been stored unused. I am selling it because I no longer use it! 【Specifications】This step-up ring has a barrel length that takes into account the protrusion of the lens. Teleconverters, close-up lenses, and various filters can be attached via this ring. Please understand that this is a long-term storage item! Please purchase if you understand that it is a used item! Please note that returns are not accepted after purchase. Feel free to ask questions or make offers. I would appreciate it if you could be considerate, as I might cry if the discount amount is too large.
