I'd rather pay $2k for a mk2 version of the 1.2L that doesn't focus shift and isn't soft wide open, than $850 for a mk2 1.4
What are you comparing the 1.2L to in order to call it soft at f1.2? There is a post above this that mentions the focus shift.
Never seen the famous focus shift and is sharp at 1.2.
This is where people have it WRONG. The 50L's top quality is that it IS SHARP wide open, the problem is that the 1.4 surpasses it's sharpness stopped down. It is sharp wide open. I'm in agreement with you on this one.
The 1.4 Canon is a good lens. The 50L though, is a Great lens.
Maybe I've never seen the famous focus shift because I can see the DOF with the EG-S screen on my 5Dc. It just works at all apertures and when I hit the DOF preview, It still perfectly in-focus where it landed. Its never been an problem on my copy stamped 2010.
The only downfall I see in the 50L is price and weight.
