I can understand that.
My point in changing was more based on the issues with the camera I suppose. Pixel peeping is something we all like to do, but I don't bother with much anymore, unless I know I missed focus and that I know was either down to myself, or the focus not locking when and where I wanted it to.
Asking about the lenses was merely an additional question...something which
might help my mind swing a bit one way or the other. I know when I was considering moving from the 24-70 MkI to the MkII, there was a mega difference for what I would be using it for, but I went for it regardless. I didn't buy new I might add and the cost to change was minimal, so I don't wish to give folks the idea I simply splashed out an extra £700 on a new lens, without it being justified.
I'm sure by the time the 5D4 comes down to a price I might have considered, the 6D2 will be out.
