The Kodak monochrome digital sensors produce a lot more resolution than their comparable sensors that have a Bayer array, gain about two stops in signal to noise ratio and about two stops of dynamic range. I still don't like the way my digital cameras or others that I've tested present the highlights as compared to a really good print or multiple pass scan from a good negative. The Nikon D2x was the closest to 'good', but it is huge and really heavy. > OTOH, if they can make a monochrome full frame sensor with much higher > tonal > depth, that would be another story. The Kodak sensors I'm referring to gain 2-3 stops of dynamic range.

The 0.95 Nocti is currently the best 50 mm lens in the Leica stable. That seems perverse to me. The 50/2 is very good in terms of corner sharpness and distortion, and its tonal rendition is lovely but it flares a lot (I am currently in possession of my fifth sample and have tested more than 10 others, they all flare if subjected to the right circumstances) and field flatness is less good than some other comparable lenses. I guess, in short, I disagree that it is 'one of the best lenses ever'. In fact I like the Pentax 43 mm lens I got from you a whole lot better than any of the six element 50 mm Summicrons. > Put it this way: > 50/1.4 ASPH - light year ahead performance wise (yes I know some people > like > the old one for bokeh, magic look etc., but you know what I mean) > 70/2 ASPH, much smaller, much better performance vs. the old 75/1.4 'lux > (yes, I know, the 'lux has better bokeh, which is why I am keeping it...) > Noctilux /0.95 ASPH, much better performance and even 11% faster!!

Simple - be the very best 50 mm lens in the Leica stable. 50/2 is a specification where they could design a lens that would wipe the floor with all the competition, including their own 50s. The current lens doesn't do that, in fact, the only thing it does better than the 50/1.4 asph is, as Erin put it "The close up performance of the Summicron is definitely better than that of the new Summilux and if you do not need the high speed, it still has its virtues". A new lens, hopefully, would set the standard and still retain the 39 mm filter size.
