With the Noctilux f/1 and 75 Summilux I also do better on the M240 with the 
rangefinder than the EVF; probably because the rangefinder is set up 
correctly (and hasn't drifted as yet) and the EVF allows too large a 
focussing range over which it looks OK to me. Focus peaking also seems to 
indicate too great a depth of field, while at f/1 the contrast of the 
Noctilux is low enough that often nothing triggers the focus peaking. On top 
of that the EVF itself and the whole shooting experience with it is rather 
sluggish; overall, that may be the biggest reason I stick with the 
rangefinder. But at least now we have a choice, and if the camera gets 
whacked, we can still focus until the rangefinder gets recalibrated.
