There's an old saying: "Good, fast, or cheap -- pick any two." While it may hold true for most things, I believe the 50'Lux could well be the exception to that rule. Although it isn't exactly cheap, it is certainly affordable, or obtainable, if you really think you want it and willing to save for it. With a max aperture of f/1.4, it definitely fulfills the name that it was given ("summi" = maximum, "lux" = light), and it's only bested by the Noctilux ("nocti" = night) in the Leica line of 50mm lenses. Just how good is it?
