got my 1st legacy lens - a five star/tou 28mm/f2.8. wondering if the gap between the lens and the adapter is normal? it's tight, no rattle, and images are fine, but it seems like it should snug up. advertised as a minolta mount, and stamped MC (which could be unrelated for all i know), i got an mc/md adapter for it. A6000, BTW, but that end works just dandy. thanks, hive-mind.
