>>3483518Yes, and what does an adaptor do? It extends flange distance so optics of lens made for dslr can function as well as it can on mirrorless body!
>>3483522Small part of it. Many moved from Canon to Sony since they could use their old lenses on it. But the largest amount came from Sony users cheaping out on lenses. Never learning or knowing of optical drawbacks of adapting lenses. Unfortunately this also gave birth to many misconceptions on their side. When some of them found the cash and bought lenses made for the system, they compared them to their performance of adopted lenses on adaptor, and the results are countless stupidities you still hear on the forums.
