I am happy that Canon up there game. I'm not a brand loyal shooter so what ever works best I use.
However it is very unfortunate that they still limit the exposure comp settings! It's a simple software tweek. And I know that Nothern lights fixes this, but it also slows down the camera. My friend has been using it for years and it would be much better if Canon would get out of this 1/3-1/2 ev step. It is just silly that they don't fix it. It would cost nothing..
MTF seems to be the most consistent measurement. Although when you consider the number of people that are new to photography this measurement seems to have some value.
I guess it won't be of any direct value to me, but it will help me explain to my friends why buying good glass is better than constantly upgrading to the latest body.
