I will likely get into trouble for a few comments on the Nikon thresds but I still wonder why I (and many others) lika' Leica Look. What is it? We say it is there. and we post truely great images, and we keep buying and showing [And I am the first to demure blind wine,(I prefer French, red and Bordeaux!) and audio tests (tubes of course!) in line with Leica glass.
I submit that the closest I see (and it has relevance in optical performance) to what I would call "space around the objects in an image" We sometimes say "3-D" sometimes "presence, life....etc." We struggle as much as the audiomaniacs (moi aussi!) to describe why record, tubes etc. have more 'presence' 'life' etc.
Is this getting close?
SUre the Canon train image (albeit against a black sky) has a 3-D quality and some of the low ISO D3 images are pretty 'airy' but with Leica, it is easy (needed for the likes of me)
So, unless you are all defecting to Canikon, let's see those images that make Leica DIFFERENT (and to us, BETTER)
PS: Saying they ALL are is an acceptable answer!
