70-200mm f/2.8 L IS II USM <- Just got it last week
50mm f/1.2 L <-Next one to buy after paying off one above
16-35mm f/2.8 L <- for now living with the 17-40mmL as that I got a great deal on it used
14mm L (someday)
24-70mm f2.8L USM II
That being said...where I have the 14mm, I might have to say I would alternate that one with maybe the 85mm L f/1.2 and the 100mm L macro.....I can't really decide on that spot...but one of those would round out my top 5 I'd like to get.
I'm making my way down the list.
For now, I have the 85mm f/1.8, and honestly, that is a fun lens, great bang for the buck, so the 85mm 1.2 is likely to be lower on the list of what I'd want to get to finish out my collection.
That is all realistic. If going for ANY lens price no option, I'd like to have a 600mm or 800mm lens top of the line Canon has, but I think I'll save to buy a house first.
