Great work Robert!
I was able to recently borrow the Canon 50/1.4 LTM and below is a quick & dirty hand held comparison of it at near minimum focusing distance (1m) vs. the Nikkor 5cm f/1.4 and the 5cm f/1.5 Summarit. Images are presented in that order (Canon, Nikon, Leitz) and shot on the M9.
For the first group, the exact same LR processing settings were used for all three, for which I selected the Nikkor as the 'middle ground,' including a very slight curve tweak.
and this is the Summarit with contrast, curves, clarity and slight WB adjustment to get it looking a bit more like the other two:
As you'll note, the Canon has considerably cooler WB.
For these below, I've adjust the WB to better match all three. Again, the Summarit is presented with an 'as shot' version, and one that has been tweaked to be closer to the other two:
I haven't had a lot of time to compare the lenses more closely, but offhand, the Canon seems to be the most 'normal' of the three, being fairly well corrected even from wide open at near and far distances. While it's not a 50 Lux ASPH, it's pretty good wide open, with a nice amount of imperfections to add some character, but not super glowy like the Nikkor (which really surprisingly snaps up in contrast and loses much of the glow at f/2). My Summarit is always pretty low in contrast, but the color quality is still great.
In some respects the Canon doesn't seem 'weird' enough to be an oddball vintage lens, but I guess it depends on what you want. It should be great on the MM though and still a solid performer in color.
