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?

As I replied on the "other forum", keep sending it back to Nikon until they get it right. If they can't get it right, they will hopefully offer you another new camera.
