I won't be going mirrorless for awhile. I had to choose between 850 and z7. I felt the 850 was better for my needs. I am back in the poor house with this purchase, so it will be a long time before I upgrade. I don't think it will be a problem as I am very happy with the quality of the 850.Pick up a D850? You gonna go Mirrorless? Nice shots. I swear in the 2nd pic from 1st post I can see you standing there in the reflection from the eye.
