I thought that too, John, but checked. The product description at B&H says "Lens mount: Bayonet Mamiya 645 AF Mount; M645 Mount can be used with strict limitations (manual focus confirmation, stopped-down metering) Also compatible with Hasselblad V series lenses (manual focus confirmation, focus aid, stop-down exposure metering). Requires optional Lens Mount Adapter #310-244 (Black) or #310-245 (Silver)"
