Fstoppers just put out Five Reasons Why You Should Switch To Sony Mirrorless. In the article they mention the new α7R IV, Sony's rapidly-expanding native mirrorless lens lineup and how high-end lighting companies have embraced the Sony system.
"[Sony is] a company that professionals want to be a part of and work with.

When you have storytellers wanting to partner with your company because they see the advantages of what you offer, that’s what your company should be striving to be. We recognize that technology makes working with equipment easier (and sometimes harder), but if what you are doing makes it more valuable for a storyteller to build on their vision, then you are going to create a movement.

It’s that which excites us as creators where our attention and pocketbook will go."
