Yes have had two of them, one on the D750 and one before Christmas on my D810. I like the feel/look of Sigma lenses at present, but I have found some focus inconsistencies on them both, along with the 24-35mm f2 and found them hard MFA even with the dock..... I would get them good at one length and then knock it slowly out at the opposite length. I have also had three Nikon 24-120mm f4 and the first two (on D750) I thought they were just okay lenses, but the last one I had (on D810) was the best, but like a t*** I sold it and have regretted it. So in summary, the Nikon versions pips it for me, but I do prefer the contrast more with Sigma lenses.
