I am a wedding photographer and have two 5D mark IIIs, a 70-200 f/2.8L IS II, a 50mm 1.2L, a 24mm 1.4L, a 100mm f/2.8L IS and three 600ex-rt flashes. I have more than what I need to take amazing pictures in almost any situation but I after I buy something I find myself looking to the next thing to buy. I don't know what is wrong with me it is like a disease. I know I am crazy and should just be content with what I have. So if you were in my situation and you were going to buy something new would you sell one of the 5D3s and get a 1DX or would you buy the 85mm 1.2? I am a little afraid the 85mm 1.2 will be a little slow focusing at receptions similar to the 50mm 1.2. I just don't understand that my 70-200 and 24mm are able to focus really well in almost no light but the 50mm is very slow and unreliable. If the 85mm is anything like the 50mm in that regard it may change my decision. I would love to use it for portraits and almost always shoot at very large apertures. As a matter of fact I love a shallow DOF so much that I usually shoot two or three Brenizer method images each wedding to get the effect of f/0.5 or f/0.6.
