I can understand this kind of price for a > Summilux or a Noctilux, but for a basic lens like this?? > It is not a basic lens. It might be a basic 35/2 spec, but it has 10 elements in 5 groups, a floating group (not element, group) for close focusing, six partial anomalous dispersion glass elements and four aspherical surfaces. It is still e39 filter size unlike the giant SLR high performance lenses and is 40.9mm long and weighs 320g. Leica says it is sufficiently well corrected that it is already diffraction limited wide open. It also focuses to 30cm but has a detent at 70cm so you know when the rangefinder disengages. How I wish the C-V and Zeiss ZM lenses had one of them. You (or I) might not need it, but it is an optical and manufacturing marvel, and anything but basic. The lens it replaces is the oldest M design still manufactured apart from the non-APO ASPH 50/2. Its performance on the current 40mp sensors shows its age. Marty
