Yes, but also Sony was an early mover into mirrorless (APS-C and FF) where they've had considerably more success. Most Sony users knew the Axx series (SLR/SLT) were dead when the A7 (mirrorless) released. Sony basically abandoned everything else to focus on their mirrorless platform and it gave them a huge market presence.
