VILTROX JY-43F Four Thirds adapter, enabling the use of compatible lenses. Thank you for viewing. This is a used item purchased on Mercari. It's a mount adapter that allows you to attach Four Thirds mount lenses to Micro Four Thirds mount cameras. *Although autofocus (AF) is available, it may not function properly depending on the compatibility between the lens and the camera body. There are scratches and signs of use overall.
