Yes the Sony a7III is my main camera. But i still bring my old Canon 400d with a 70-300 as a backup but also to have the long reach since i don't have a lens for my Sony with that long focal length yet. Would 100% recommend this camera if you want to really invest in top camera gear. In my mind the A7III with all its features at a $2000 price point in the US (more expensive in Europe..) makes it the best of its price class.
