Peter, you have a way of summing it up directlyI like the SIZE of the A7r and I don' like the PRICE of the M240 - I don't SEE a better file from the M240 than I get from my M9. My MM is the most satisfying camera I own.
I can't use focus peeking to shoot wide open with my Noctilux and nail a person's eyes every time - I own a lot of fast Leica glass to shoot wide open - so the M9 and MM are my go to choices for now a far as serious rangefinder work goes.
I like being able to use Leica glass on the Sony - but I will buy the Sony 24-70FE lens to pretty much stay glued on the A7r - because the Sony SIZE for RESOLUTION equation is huge winner.
All that has changed for me is the price of entry into larger prints ha come down to reality. The Leica/Nikon systems I run - still can't do what my Artec and Alpa gear does as far as tripod work goes. I don't expect this to change - ever. I am glad I stopped upgrading MF digi backs at 40 megapixels.
I won't be buying into MF CMOS either - CMOS files all look the same - from every manufacturer out there- they are all the same - no pop straight out of camera.
I've come to a similar conclusion … in today's over-crowded camera market, with all sorts of cameras that meet a vast majority of needs, there is a new user skill that is required: The art of knowing when to stop.
I should have stopped at my M9P which had the CCD mojo I feel is missing with anything else. The MM is also my most valued rangefinder ever.
I did do a course correction and sold all of my Hasselblad H4D/60 gear, and now have "stopped" at the S2.
The A7R is, as you say, likable due to the size and relatively reasonable price for what it is capable of.
However, I process work from my gear and that of all the different second shooters and assistants I hire. Canon, Nikon, Sony, Pentax, and a few others … all CMOS, all homogenized in look and feel out of the camera.
