I have a D850 and a Z 7 with a Nikkor 200-500mm that I use for bird photography. I’m having some problems getting consistently sharp images using the Z 7. The D850 images are the reverse… mostly sharp with some poorly focused.
Both cameras are set to - M at 1/1000 sec. at f:8 with a focal length of 500mm, and Auto ISO. I use a fill flash with a Sync speed of 250 S on the D850 and 200 S on the Z 7. Both cameras are set to Single point focusing with spot metering. All shots are hand held with VR turned on.
Could it be that the lens’ built-in VR works better on the D850 than it does on the Z 7? I thought at first that the Z 7’s AF was at fault, but I would get a sharp image once in a while - killing that theory. Could it be that the D850’s VR is a stop or two lower than the Z 7’s VR, with this lens?
