Sony A99 Footage with Nikon Mount Lens

So as you guys know I was playing with some Nikon lenses. I did take a quick shot to show what detail the A99 has and handheld with steadyshot. I shot very numeral (as I typically do) because I do all the color grading in Color. Im wondering now if I want a 85mm lens. (of course would rather have CZ, glass over the Nikkor, although it is surprisingly sharp.
