I don't mean to be pedantic, but I want to clarify your statement: you mean that the Noctilux
has far more vignetting, right? Since I have no direct experience with the Noctilux, but have only seen photos taken with it wide open, I just want to confirm that.
Now, there are two different codings for the "Summilux": pre-asph E46, and the ASPH. I'm not quite sure which one of those two exhibit more light fall-off wide open, since the shots I've seen taken with both show similar fall-off (aka "vignetting").
Anybody out there with a before/after comparison of shots wide-open taken with a 50mm Summilux (either) coded?
