I started to use an NEX 7 (Buy on on Amazon.com Sony NEX-7 24.3 MP with 18-55mm Lens or Amazon.de Sony NEX-7KB Kit inkl. 18-55 mm Objektiv ). I am sure if it would replace my Canon 5D. Right now I think that I need to get more experience with the Sony NEX 7. For people I may continue to use the Canon and lovely lenses. For the rest I need to see.
I do expect that Images like the one below will be done with my SON NEX 7
