Never you mind Grego, brutha, that boy is a 120-300 shooter.

Nuff said.
Best 300 2.8 i can get for a great deal. I got mine for 1775(final price). Tough to beat that., especially on a college students budget.
But as of now, I'll have
2 bodies (30D + 1DMKII)
16-35 2.8L
50 1.4
70-200 2.8 IS
120-300 2.8.
In 2 years work with lack of consistent job.
I'd buy the 50 1.2 if it was going to be my workhorse lens though. It's worth it then.

If you have a crop body (1.6x especially but 1.3x also) then the 35mm f/1.4L would make a better, more usable lens IMO.
On full frame bodies, the 50mm f/1.2L would similarly represent "the ultimate standard lens."
How far you want to go is something only you can decide.
The biggest thing about the 50 1.2L is that its the 85L 1.2(on full frame), basically. The 1.6 crop user would have a very long high quality lens. The 50 1.2 gives some more flexibility if you do portrait stuff. So if it is a quality lens like the 85L, then it fits a niche, as a lot of ppl use a 1.6 crop camera.
