I shoot with a Sony a7R3 and the 100-400m m Sony GM lens. While I am generally satisfied wit the lens performance, i noticed on some images I am getting a shading along the image as if it is out of focus or is astigmatic. I have attached one of these images reduced in size and cropped. Please look at the left side of the Hawk's body and bring the image up insize on screen and you will see the shadow like area following the contour of the left side of the bird's body. Any thoughts about his would be appreciated.
