this brings up an interesting point about the current and pre-asph summilux
35. There is a similar argument to the above that the latter, because of
flare, puts in more shadow density in high-contrast nighttime lighting
conditions. I'd have to say that subjectively, that seems true. I've
assumjed the overall veiling flare from bright highlights eg streetlamps
bumps up the shadow threshold, at the expense of overall contrast. (In a
high contrast night shot this is not such a problem).

 I don't want to open up the asph v. non-asph debate but I wondered if this
is a real effect or just my wrong impression?
