Condecending if nothing else.. that is great. Of course i don't do meaningful photography, that is your domain o-great one!
If you want to test quantifiable things, tests are what you have to use. Level of detail and level of noise, those are things you have to use tests to determine, quantifiable, where are. The Leica have far more detail than the d700 at base iso, both beacause it is a higher resolving sensor, and beacause it do not have a AA-filter. This is quite easily shown. At higher iso, the d700 has less noise, but also less detail, to about iso5000-6400. What you are seeing, i can not control, but I can control test methodology, and the "science is stupid"-attitude some people seem to have, is great, just don't apply it in the territory of science. What am i trying to say? If you think an image is great, noise or no noise, fantastic! But then don't participate in a technical debate about noise levels, beacause you are in the wrong thread.
