Well possibly good news after the horror stories in another ongoing thread here.
I bought a 70D today, having had issues with the model in the recent past.
I am thrilled to say, all the issues with my first copy have gone.
I have tested the new body with an 85 1.2 wide open, a 70-200 2.8 v2 wide open and a 100 2.8 L macro wide open.
There are no focus errors at any distances (asides the ones that are my fault) and the image clarity is superb.
I don't know if there has been a manufacturing/process change but this copy is flawless.
