Doug,, this is about focusing for amateurs/mere mortals, of which I think
you are well above.....and I did define it as so.....

MF, and especially M cameras, are less than optimum for accurate focus using

are not optimum. 

Sorry that you do not like my prediction of the future of cameras.....  in a
few years, we will see whether the prediction was right....  You are, of
course, entitled to your own opinions.
