Since the Nikon 50 f1.4 and 福倫達 40 f2.0 F mount are not very popular in Canon community :) May I ask Nikon chings for your comments?

I have 5DII and Canon 50 f1.8 and F to EF mount adaptor.
Want to buy a better prime len, manual focus is ok for me.

After reading some posts, i have the following choices:
(1) Sigma 50 f1.4 ~$3xxx
(2) Canon 50 f1.4 ~$2xxx
(3) Nikon 50 f1.4 (F mount) ~$2xxx
(4) 福倫達40 f2.0 (F mount) ~$2xxx

Any ching have the exp. using (1), (3) and (4) in Nikon FF and how about the pq of the comparison of these lens? or any other recommondations for the standard prime len? My budget is below $4000.

Thanks u very much
