Kristian,
I think you are teasing us with your claim not to know the Leica look. The superb images taken with the Noct which you recently posted are a perfect example. Those are the kind of images I associate with Leica glass. I can get beautiful images with my Nikon kit... but they simply do not look the same.
Well certainly the Noct has a unique modern Leica look as it cannot be replicated by any other lens on the planet. Though the traditional look people talk about is not the same thing people are referring too these days.
I would bet that if I shot my Nikon D3s with a Nikon or better, the Zeiss 35/1.4 and compared to another photographer shooting a Leica, most would have a hard time telling the difference, especially because of today's processing tools. In the old days it was easier to analyse the chromes on a lightbox or projector.
Most of the shots people guess were taken with a Leica in my folio weren't, because I shot them in good lighting and I know how to get the most out of each lighting setup. This is a big part of the overall result. IMHO, the very best lenses for 35mm are some of the Zeiss ZF/ZE lenses for SLR's. The very best 35/2 in the world is the Zeiss ZF/ZE, and same with the 100mm, 21mm and maybe even the 50/2 Makro.
As much as I love the Leica M system more than anything else, I am not a believer in the 'Leica look' being superior to everything else. I believe in my abilities to use the most suitable camera for the job, and to do the very best I can with it.
