So if you have a 12mm prime, how do you place a MTF chart at infinity?

It's a good point, but I think that the original argument is valid; MTF tests are more useful when they reflect real world focus distances.

If you want to test the MTF of a 14mm lens, it's better to use a wall sized target at 2m than a poster sized target at half a meter.
