Ive been reading up on this lens for a few years now, but always kept away because of the reviews. I decided to finally give it a try since i love my 85mm 1.2 soo much! In my opinion its a great lens. Theres many that say it has a problem focusing, but guess what, its a 1.2. It has no problem unless shooting as this extremely shallow DOF. It misses the same amount of shots as my 85mm 1.2 but focuses faster. It not as sharp as the 85 but nothing that would stop me from buying it. The L quality is still there, and if you dont need a lens that will last for a lifetime, get the 50/1.4! After reading alot of these other reviews i start to wonder if Canon has worked on this lens since it first released, or if people just gave it bad reviews based on what they heard from others? I guess ill never know, but have to say im really enjoying my copy, and dont regret the purchase at all. Im using my copy on a 5D-2 and wouldnt think the 50 would be as usefull on a crop sensor. After running some tests and pixel peeping at 100%, im pretty happy with the shots. Wide open its good enough for an L, and gets much better when you step it down, and that when the quality of the L series really shows over other 50'S.
