I agree with KameraKev. I started with Sony years ago with Nex 5N, passed through many up to A6600. I bought my first Sony full frame (A7r3) a couple of years ago for bird, landscape and city shots. I sold my A6600 to buy the A7c, which is my travel and street camera. Sony has made the transition seamless. VERY happy with results and how much I have learned over the years.
