I have to disagree with you on point 3. In the old days photography is a very expensive hobby, and therefore manufacturer often do not have cost saving in mind they tend to use high quality material for the glass, what is lacking in the old days is computer design and the latest coating technology. But IMO, the glass quality can sometimes made up for it. Modern lens often are design with costing saving in mind and try to balance between quality and cost. Also, in the past there is less restriction in use of material in glass, things that improve optical quality like lead, various rare earth or radioactive material can sometimes be found in legacy lens. Modern lens often plastic lens inside, if you think about the difference in optical quality for plastic lens and glass lens (or even crystal), then you know what I mean.

They always say that. "Good old lenses with glass and metal". Sure. But I can't remember any, say, 50mm lens that is sharper than NX 45/1.8.

This "pure glass" in old lenses makes no sense if it is worse than modern plastic (well, glass-and-plastic sandwich in some elements to be correct).

And if you will look at the cost of old 85/1.8 lenses like Minolta - it costs the same as modern Samyang 85/1.4. Sure, if you need something special like swivel bokeh you will go for Helios-40 85/1.5 (or its "father" Biotar) or cheap Helios-77 (which is a better version of wide-spread even outside of CIS Helios-44 lens) for 50$ or so. I used to have the last one. Nice toy And this kind of bokeh can be used in some cases, but not all the time. But you really wont use that if you have NX45.
