I decided to retake this with my new Sony A7R III camera and all I can say is wow! I think tomorrow I'm going to go to the park to take some nature shots with the camera and Sony FE 100-400mm F4.5-5.6 lens.
The thing I link about FF Mirrorless camera is the EVF for I can see what the picture is going to really look like before I press the shutter button. With my old DSLR I had to totally rely on my photography training with the light settings. Don't get me wrong it's very nice thing to know, but for some reason a lot of my shots didn't come out the way I wanted to. Most of them were focusing problems and the AF on the A7R III camera is fantastic (I hear the A7 III and A9 is even better).
