Some observations... I'm crazy about old lenses with little contrast, and the CV 35 classic single coat makes the f8 shots look like trix pushed 2 stops in terms of contrast! Not what I was expecting at all...
The other thing I remembered about the nokton classic is that its too small for me (large hands!). I tried it once for handling on a friend's RF and I think that the aperture & focus tabs, while good, are too close together to fiddle in the type of photography that I do. Leica does it better for handling, then again, there's a price difference to pay too.
Otherwise, I think its a commendable lens. Just doesn't fit me too well.
