This is an electronic mount adapter for using Canon EF mount lenses on Fujifilm G mount cameras. It supports AE/AF. I purchased it new from Map Camera about a year ago. Retail price: ¥72,900 (tax included) Operation confirmed, with almost no scratches or abrasions. This is the only EF adapter with a variable ND filter, so it was very useful for video shooting with EF lenses on GFX. Fujifilm GFX canon EF
