[Leica] Do I really want a 75 Summilux?

[alal at duke.poly.edu (A. Lal)]

Vick,

May I suggest that you get the 75 Asph Summicron instead? Optically, it has 
a much higher degree of correction and suffers from none of the faults of 
the 75 'Lux. With a digital camera such as the M9  that one stop difference 
in maximum aperture will not matter as much  now as it would have back in 
the day when everyone was using K'chrome and Adox KB14.

Regards,
AKhil
