Hello, Eric. Just providing you an update. I live in Alaska and since I returned home temperatures have been near zero F so I have been unable to set up and take some shots as you requested. The forecast is for warmer daytime temperatures this week. So I will be able to do so by end of week.
I must point out how frustrating this entire conversation is. The photos which I already submitted are consistent with the methodology indicated on the Nikon support website for fine tuning AF. Following is copied directly from the website:
1.Fix the lens to the camera and place the camera on the tripod. Do not move the tripod during testing.
2.Autofocus on a flat object such as a hardback book or small box which has fine detail a fixed distance from the camera.
3.Place a ruler at an angle of 45 degrees or more beside the object as shown below.
4.Align the flat surface of the object with a selected measurement point in the middle of the ruler.
5.Using autofocus, focus on the flat surface of the object and then use focus lock. Keeping focus lock, photograph the ruler at the point next to the flat surface.
This describes exactly the setup and methodology that was used in taking the photos which I've already submitted. Presumably you can see how from an outside perspective this seems very strange that Nikon support does not comply with its own company endorsed recommendations for testing AF.
I will continue to pursue the photos that you have requested. As indicated they are weather dependent due to time of season in Alaska.
