I'm a DSLR user, but plan on buying a mirrorless camera soon, possibly a Fuji. While reading about their cameras, I noticed that some of them, along with an EVF, also have an OVF. My first thought was, WHAT??!!! I really have little knowledge of mirrorless cameras, but I always thought OVF was a view looking through the lens, like the DSLRs. How is this possible with a mirrorless camera? It's possible the answer to my question is right under my nose and I'm missing the obvious, but I'm just not understanding this. Any explanation would be appreciated.
