Adapting DSLR lenses of all kinds to your mirrorless camera has long been one of the coolest things about going mirrorless. It has also made that process of transferring from an old DSLR system to a newer mirrorless one that much easier of a process for a lot of photographers.
The caveat being that the majority of these adapters are just dummy adapters, meaning they hold the lens in the right spot, but there is no AF or electronic communication to the camera. . thephoblographer.com
