sorry John,  I am not being very clear here trying to communicate.  I am 
sorry. My point actually is  quite simple. Because of their narrow depth of 
field wide open, a Noctilux and a Summilux 75mm/1.4 are the most difficult 
to focus of all lenses when shot wide open at a subject that is close. So 
yes, while they have prominent oof areas in the final image, they are most 
unforgiving, and require the most accurate and careful focus of all. Many of 
us find a significant miss rate on a Leica body, in my experience from a M3 
up to an M9.  This may be due to a rangefinder not perfectly adjusted for 
this purpose, or to our eyes, or to other random errors. In my experience it 
is far easier to accurately and reliably focus these lenses on an EVF with 
magnification, giving a hit rate of almost 100% success. Even my 
recalibrated and adjusted (by DAG) M9, for my Noctilux, does not even come 
close. So in terms of ease of use and outcome, I am impressed by the results 
I obtain with an EVF and magnification, shocked, as I had not expected this. 
Part of this is due, no doubt, to the reality that you are focussing 
directly on something that you see. With a rangefinder you are depending on 
a mechanical linkage, to focus on  an object presumed to be where your eye 
sees it, in a separate window.

Yes, it would be nice to have a "full size" sensor, nicer yet to have a 
sensor 3x "full size"... but nicest of all to be able to focus truly 
accurately, as well as quickly and reliably.

Steve
