Great quality EOS to mft mount for Canon EF lenses only!
High quality. Nice fit. Less likely to get this adapter stuck in the lens because of the release lever. Don’t buy cheap one 14 bucks adapter. One of my lenses got permanently stuck with a cheap Fotodiox adapter. Be careful! I am using this adapter with 70-200mm f4 zoom L lens. Works like a charm. No loss in quality. Read other reviews on how to use various size f stops. Works only with Canon EF lenses (with a red dot). DOES NOT WORK with EF-S lenses (White dot).
