Samsung couldn’t have been more obvious, naming their entry into mirrorless NX (Sony’s was NEX), using an APS sensor (like Sony’s), and coming out with similar lenses (both had 16mm primes early on). Put simply, they wanted you to buy a Samsung mirrorless camera instead of a Sony.
Since then, the two companies seem to be on different paths, though. Sony transitioned to Alpha and quite different designs, while Samsung began putting a Tizen operating system in their cameras and connecting them more directly to their mobile platforms.
Recently, rumors of Samsung withdrawing from cameras have become prevalent. Make of that what you will, but new bodies and lenses from Samsung seemed to have dried up in late 2015, with no announcements in 2016.
What will probably surprise you is how many mirrorless cameras Samsung has already generated in a few short years:
