#151. "Reikan test on 70-200VR I and D800" In response to In response to 0 Thu 28-Feb-13 09:55 PM by Mako

(Apologies if this is not the right place to post this question. But wondering if other Reikan users are coming up with similar results for the Nikkor 70-200mm VR I)
I am using Reikan FoCal Pro for the first time. Using D800 and Nikkor lenses. Still much to learn, but so far I'm fairly pleased with the results. Tested two primes and two zooms with expected and approximately repeated results. My challenge is with the my fifth lens, the Nikkor 70-200 VR I. Here is the result at 3 focal lengths:
70mm = AFMA +4 130mm = AFMA +9 200mm = AFMA -1
Sharpest Aperture = f2.8
1) I didn't expect AFMA at 130mm to be so far off relative to the AFMA at 70mm and 200mm. I can actually see a bit of difference too in actual use when comparing AF vs manual focus at 130mm. Is this typical of this lens? Are the results fairly acceptable? Or should I send it in for recalibration?
2) Sharpest Aperture at f2.8 surprised me. All other lenses tested came in anywhere between f4 to f13. Again, is this typical or do you think I have a bigger problem?
Oh, I'm assuming I'm using FoCal correctly. That could be another issu )
