【Product Overview】 This is a mount adapter for Canon EF mount lenses to Micro Four Thirds mount. Please check the compatibility of your camera and lens via a web search. It's a bit pricey, but it's like new, so I think it's a good deal! 【Condition】 I bought it new and only attached it to a camera once. It has been opened, but it's the same as new. 【Reason for Listing】 I accidentally bought it, but I couldn't return it because it had been opened. 【Shipping】 I've set the shipping time to 2-3 days, but I usually ship the same day if I don't have any urgent matters, or the next day depending on the time of the order.
