Except of course it isn't. Apples to apples (if maybe red apples to
green apples), with fast shutter speeds and low ISOs to show it off, the
amazing 75mm Apo-ASPH Summicron at f/2 beats it obviously in contrast,
fine detail, corner goodness -- whether the Summilux is at f/1.4, f/2,
f/2.8... or maybe elsewhere. And the Summicron is shorter and lighter:
all-around handier.  I cannnot tell a lie: I own the 75/2, and I use it
whenever I can, like when I expect for the light to be reasonably

But the Summicron doesn't go to 11.  I mean f/1.4.  So using it, I'd
have had to try to hand-hold twice as slow a shutter speed.  Might not
have worked.  There are also some touchy-feely differences in the way
the lenses render stuff.  But basically...  f/1.4 is darned handy when
there isn't enough light.  Because the next ISO up is really raggedy
looking, and the next shutter speed down (1/45) would've been pretty
wobbly for a 75.  Even 1/90 can be hit-or-miss.

I'm glad you see my point, Mark.  I know you're a big fan of compact,
light, slow, super-duper-sharp lenses, which make sense for someone like
you who apparently goes outside a lot.  For much of the day, there's a
really bright light turned on out there; f/4 is practical.  So you often
make fun of the large, heavy Summiluxen they've been introducing.  But I
seem to find myself making about 80% of my pictures in rooms at night,
and an excellent fast lens makes me really happy.
