This seems strange since it works with the older Nikon D3 and D3S models. However, ALL of the newer Nikon cameras in FX, and DX have to be calibrated semi-automatically / manually which means I have to stand there dialing in the numbers for the software when doing AF Fine Tuning because Nikon now does not interface Reikan software to change the AF Fine Tuning. Luckily for me, two of my full frame cameras are still D3S models which use the full auto calibration features of the Reikan software, which is delightful to use. I've changed a lot of my gear this year so have been doing a lot of lens calibrations with Reikan Focal Pro. I know there are other threads on camera calibration methods but I feel like we have a missing that Nikon could do something about to make all of our lives better.
