I own a Nikkor 500mm VR lens. It is the single most expensive piece of photo gear that I possess. But I also have several other pro grade lenses and bodies. All in all I'm heavily invested in Nikon and all of my gear is registered with them, the point being that they can see that fact.
Their customer service system requires you to enter service requests on-line prior to sending equipment to the service center. I recently did so for my 500VR. The focus needs adjustment. I sent in a set of images taken on three different bodies that consistently showed the same issue. The images were of LensAlign Pro targets designed and sold specifically for the purpose of focus tuning. Also one can find on Nikon's support site the following which describes the same method of focus tuning:
Here is the on-line support message exchange with Nikon.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.
My original support request:
Nikon's reply:Lens was tested on three different camera bodies, D4, D810, and D800E. AF adjustment of +10 is necessary on each body to obtain proper focus. With 1.4x TC installed proper focus can not be obtained at all even with AF adjustment set to maximum of +20. Same results on all three bodies. I was able to complete shooting last season by avoiding use of TC. This is unacceptable for ongoing use of the lens. Use of TC must be possible for my shooting requirements.
Am I missing something here???Thank you for contacting Nikon & I do apologize for the issue you are having. May I please ask if you have any sample images of people or anything in nature as we cannot advise on focusing charts?
