I personally wouldn't get the 50mm f/1.2L because I do not shoot in low light and I never use apertures wider than 2.0 at 50mm. If you want better, all around coverage at 50mm, the 50mm f/1.4 and f/1.8 are nearly as sharp or sharper at 2.8 and above. Also, in my experience, the 24-70L zoom lense performed just as well as the 50mm f/1.2L at f/2.8. So if you don't really really need that narrow use of a 50mm lens, there are better lenses. Unfortunately Canon does not make a 50mm lens that is super sharp across all apertures. I wish they would make one comparable to the 35L and 85L. You almost have to buy both the 50mm f/1.2L and the 50 f/1.4 or 24-70mm L to get full aperture coverage from Canon at 50mm. Good luck!
