focus calibration varies with focal length of zoom lenses
In reply to wireless, Dec 8, 2012

I calibrated my Nikon lenses with my D800 and Focustune (which is easy and a joy to use).  I tried 3 different focal lengths for all the zooms to see the differences. I used a tripod, mirror lockup, shutter 2 sec delay, and cable release.
THe only major differences were with my new 70-200 2.8.  Do you think these results warrant a return to Nikon for this lens?
FOCUS TUNE adjustments (* lengths had the most fine tuning):

1. 24-120 f4
    @ 30 mm  0
    @ *85mm  -3
    @112mm  -5

2.  14-24 f2.8
    @*14mm  -5
    @*20mm  -5
    @24mm  -4

3.  70-200  f2.8
    @75mm   -10
    @200mm  -4
    @*122mm  -16

4.  18-35 f, 3.5-4.5
    @18mm  -5
    @23mm  -5
    @*26mm  -7
    @35mm  -10

5.  10.5 mm f2.8 dx   -6

6.  80-400 4.5-5.6
    @400mm,  -5
    @*240mm,  -6
