Unfortunately, too much play in the bayonet, unreliable data connection

Made my copy, as in other, initially a good impression seemed to be well finished and made of ordinary materials, and unlike many a bad experience with the parallelism of both bayonet levels I had no problems with fast lenses with blurred edges. Unfortunately led the radial clearance in the bayonet on two different cameras to similar problems with virtually all lenses that sometimes namely demolition of contact. On a brand new E-M1, it could be even provoke reliable: moving after snapping links to the left boundary of the Game, contact there, right away Contact. Buy used MMF-2, no more problems of Viltrox unfortunately had to. Too bad, here it obviously needed really just a smidgen closer tolerances in the manufacturing and final inspection. And when the adapter would therefore cost five euros more, it would still be cheap! The astronomical prices that are demanded for the original accessories, nevertheless fell slightly to undercut.
