rather than a cheaper lens?  At f/8 or 5.6, probably not much, unless it's 
what you've got anyway.

But at f/1.4 or f/2, the real benefit of the 'Lux Asph is not the

f/8). It's that you get a crisp, contrasy image that looks better than 
pretty much any other f/1.4 lens out there.  Take a wide-open picture with 
a 35/1.4 Asph and its predecessor, or a 35/1.4 lens by Those Other 
Manufacturers, and you'll see a difference on a digital sensor.  Just as 
the differences are visible on Tri-X or even faster films, and on a humble
