Thank you for viewing. This is a Canon FD to Fujifilm X mount adapter. Please check the manufacturer's website for specifications. I am selling it because I changed camera models. It is in good condition as I haven't used it much. I will pack it carefully and ship it via anonymous delivery. Please consider this item with the understanding that it is a used item. This is a new K&F Concept mount adapter, which allows you to convert FD lenses to FX mount. - Brand: K&F Concept - Model: Mount Adapter Thank you for viewing.
