Larry:  I have a Canon 50/1.2  It is pretty much as you describe it.  
The M8 cuts off the worst part, but the lens is still a compromise 
design.  Sometimes this is "character," and sometimes its just plain 
soft.  I have a relatively clean and good sample.  I would probably sell 
it if I find a decent deal on a Konica 50/1.2 or the new Nokton 50/1.1, 
or if I ever score a Noctilux at a garage sale...  Meanwhile, I have it, 
and it's fast.

That said, a little local contrast enhancement or selective sharpening 
makes things right.  Focusing is tricky, to help this, the focus ring 
has a long throw like the Noctilux.  It's probably best to "rough" set 
the focus ring, then sway your body to fine-tune the focus.

Here's a decent one, wide open, with the local contrast boosted a bit.
And a few more, wide open:

Stopped down, it's quite decent, just a little local highlight bleed and 
veiling flare. This is a drastic crop, about 50% magnification (1:2)--I 
had just come out of a dark pub, and spotted this across the street, no 
time to change lenses, so I just shot.  f/11, I think:

A lens hood is a must.  I got a cheap 55mm screw-in.

Hope this helps!
