Haha yeah. It is either the 1.8 or 1.2 for Canon users. But at the moment can consider the Sigma 85 f/1.4, I heard about RM2600. Pretty good price.
I've used the 1.2L before for event with both 1Dmk4 and 5Dmk2, horrible experience. Initially friend switched with D90+70200 and he borrowed me his 5Dmk2+85L. Shoot a lot of out of focus, downstep to f/1.4 also bad accuracy. Then I thought its due to 5Dmk2's lousy AF system, took his 1Dmk4 instead. Also same case LOL. Thought my focus method incorrect, cause that time I don't own any big aperture lens.
Until recently when I bought my own 85G, I finally realized how sucky Canon focusing system is indoor

. Canon may focus faster than Nikon, but hit rate is bad especially the 24L, 50L and 85L. The 100L seems ok though.
I see that you are having hard time handling big aperture lenses. Perhaps you should stick to lenses above f2.8 considering you mentioned that 100L
seems ok.
Let me enlighten you a little, testing a lens is not like eating nasi lemak where you get to taste everything the moment you swallow it down your throat. You'll have learn its characteristic and it takes time to understand it. You might have screwed up your first experience with those premium lenses due to your inexperienced handling in big aperture lenses but if you were to conclude saying all of their focusing sucks then I would suggest you to just stick with budget lenses.
On the other hand, focusing on 85mm f1.4 is obviously a lot faster compared to f1.2. The F number is already obvious unless you have difficulty in differentiating between f1.2 and f1.4. I own a 85L and also a Sigma 85mm f1.4 HSM. The Kegma beats my Keg in focusing speed significantly, I wouldn't deny that. I own a 5D2, 1D3 and 50D and I hardly need to whip out my 1D3 to shoot just because my 5D2 focusing forces me to do so. I own close to 20 Canon premium lenses and the lenses which actually gives me some 'challenge' in focusing is my 85L and 50mm f1.0. I wouldn't blame them cause they reward me heavily when I manage to tame them.
Also, if the focusing is really that bad, I guess those NatGeo photographers must be damn noob to have use Canon whitey bazooka to shoot. Same goes to Olympic official photos. Almost every big events you can see whiteys don't ya?

@bold : Must be user problems. I handle 24, 35, 50, 85, 135 and even 200L all can get in focus. Hit rate is very very high with MKIV or MKII.
LoL, couldn't agree more. Very obvious user's problem. I fully agree that both my Canon EF 85mm f1.2 Mark II
L USM and Canon EF 50mm f1.0
L USM are slowpokey lenses. They are damn hard to tame
when I first got them, once you get used to handling big apertures, your hit rate will certainly improve and you'll start loving them.
