Not sure what you mean by autofocusing mechanism. I see that the lens extends when focusing. Provides a nice scale on the front barrel. Also, the front element is deeply recessed, so no hood needed. A small and light package. I'm interested, as I don't have a 50mm for my A7. And the price isn't too much compared to some of the other 50's.
