I think when you have the 1.4 you do not need the 1.2 as for the increased low light capacity.
What makes me curious about that 1.2 lens is the 9 instead of 6 aperture blades.
Just curious by now ...
Robert,
The Nikkor 50/1.2 Ai-s is nice enough that is one of the few Ai-s lenses that Nikon still produces, new, today.
The difference between it and the 1.4 isn’t so much about the small extra light capturing ability as it is about the rendering, which is fairly different from the 1.4. Most think so, anyway.
You can get some idea of the differences by comparing them on flickr, looking up results for each lens.
First the 1.2

Then the 1.4

If you want creamy bokeh, the 1.2 Ai-s is hard to beat. YMMV as always.
