Its a tad soft wide open and has a bit of vignetting but otherwise (based on test results) looks like a really nice lens.

Will you test it?

I think you also didn't test the 105 VR in FF.

Well, almost. There are some minor traces left in 100% view and I'm sure they could be emphasized with really nasty light, but for everyday use, the lens is free of bokeh fringing.
