If money was no object I'd get the IQ180
+1
+2
Personally between the 1Dx and 5d3 I chose 5D3 becasue I am trying to get away from Integrated battery grip cameras I dont need the added bulk.
the 5d size is just right for my uses.
you really need to look at what YOU need and base that decision on those reasons especially if money is no object, that may be true but if size is an object it eliminates 1 series bodies.
