Finally, after months of hesitation and after a billion of reviews and different opinions, I got  my brand new Canon 6D, my very first Full Frame camera, and despite my many doubt, about the body, viewfinder, SD cards, etc... I have to say that I'm really happy with this camera just after a few test shots. I'll probably going to do a proper review in the next weeks, especially with my other recent purchase, the Canon 17-40mm f/4 L USM, and I really want to see how is going to behave with that body.
Anyway, here there are a few test shots, nothing special, just random shots, but I've already noticed how good are the High ISO performances. The noise is really well controlled, there no banding at all, and in general the noise is really pleasant.
50mm - f/2.2 - 1/125 sec - ISO 6400

What do you think? These 6400 ISO are very usable, even for my quite strict standards. You can't even imagine how I feel to use a 50mm or my beloved 35mm L at their actual focal lenghts. Here some other test shots I took today.

50mm - f/2.2 - 1/500 sec - ISO 800

50mm - f/2.8 - 1/500 sec - ISO 400

50mm - f/2.2 - 1/320 sec - ISO 800

50mm - f/2.2 - 1/160 sec - ISO 800
