those were f2.0, because focusing on f1.2 is very hard task - so think to modify another Nikon DK-17M - just try on from my 5D - really helpfull.
and have to say rokkor 58 f1.2 has completely different look from FF body - i think it is more foveon and crop factor job in rescpect of creamy bokeh and overall look.
Those were included into the frame with intend and i guess every fast lense will do the same, page 4 in this thread the very top message from Shuko
Canon fl 55 1.2
It's hard to know without using both lenses on the same body with the same processing? I think the Sigma SD14 is going to produce a different / better file then my old 10D? But yeah the Rokkor is a great lens, also 3 x the price of the FL.

You might say that I'm biased, but somehow I still like the Bokeh and the color of Rokkor 58 over that of Canon
It has more POP for me.
However, as I said before and IMHO, the king of SMOOTH bokeh, even though it only goes to f/2.8, is Volna-9.
