Very good workmanship! Had a precaution also a 3 times as "expensive" comparison model of a highly acclaimed competitor bought having rather more game than the estimated model here. Mechanics is going fantastically supple and soft. Great opportunity to revive old shards. Am thrilled. Have the same order again. Thus, the adapter can remain on the lens because it is much easier to solve the MFT mount to make the fiddly Canon FD bayonet than in any change.
