My D800 after Nikon service shows great AFA diviation
11 months ago

Hi all,

I shipped my D800 to calibrate and fix it's left focus issue which was confirmed to have that know bug.

I sent the camera together with my 14-24mm and the 80-200mm f/2.8

The 14-24 was sent because I tested the camera with this lens. The 80-200 was send for a regular calibration after being at my disposal since 1996.

Yesterday I used LensAlign MKII with FocusTune to calibrate my lenses and I was amazed to see that the above lenses shows perfect AFA value of 0. There is a slight shift to +1 when shifting from 14-24 and about the same with the 80-200.

However, I have a couple of lenses that I didn't think need service since they had sharp results with the D800.

Now, after the service, the nikon 50mm f/1.8 needs over +20 AFA and the nikon 24-70mm f/2.8 needs +15 @ 70mm.

I don't want to rush into conclusions but it seems that the camera was "fixed" by biasing the AFA values internally with the lenses I've sent them.

What do you guys think?
