Compared my 50mm/1.2 vs 50mm/1.4 lenses
I shot 1.2 1.4 2.0 and 4.0.
I cannot honestly see a difference as far as sharpness goes. The lenses are probably beyond the limits of the K10D camera.
I did notice the 50mm/1.4 had a touch more contrast wide open.
I dunno if it is worth it or not now... $500 for the 50mm/1.2 and $200 for the 50mm/1.4 (+AF)
Comparing Fa 50 f1.4 to A 50 f1.2
Fa 50 f1.4 is CA prone, not sharp until f2 or so like most of the 50mm lenses across brands. The bokeh is neutral at best against various types of backgrounds. The lens does not take bright lighting too well at all. Better used indoor.
f1.2 in A 50 f1.2 makes the lens a fun one. It tests creativity of an individual in how to effectively use this wide aperture, composition skill.
Still, A 50mm f1.2 is softer and less harsh comparing to 50mm f1.4
If you look at this image, the bokeh is still quite bad...
The left upper corner has the tramtrack pattern bokeh - distracting
A serial array of ring like bokeh above the entrance of the background building - harsh edges
Tree branches turns out a few bokeh rings, greens tend to have nasty smudged look to it instead of being soft and creamy.
The highlight bokeh on the roof (right upper corner) is again quite harsh with strong edges.
But Fa 50mm f1.4 can be worse in these areas.
