I just got my Nikkor 50 f/1.4G and I love it. It is fast focusing – but not as much as I had hoped – it may be slightly slower than the original f/1.4D, and definitely not as fast as my 24-70 f/2.8 which is strange as it is longer/larger lens. The best part of it is the creaminess and beautiful contrast. It reminds me of Canon’s 85 f/1.2L II lens – which I loved! The Nikkor version is way faster focusing though. In summary, the focus is fast, not blazingly fast, the bokeh is rounded and the out of focus areas are creamy.
Creaminess at 1.4 and sharp where it needs to be:
As a comparison, here is the 1.4D at f/3.5 notice the more edgy bokeh:
