Hope someone can help me to decide what to do please! I have an EP2 and a Leica X1. I mostly use my cameras for travel and am just getting used to the X1 which takes great pictures. The problem is that since I have been using the X1 I'm now dissatisfied with the 4/3 sensor and I'm looking at exchanging the EP2 for a Nex 5 because it has a larger sensor. My dilemma is this: I also have a Nikon D40 and a few fairly ordinary lenses and was thinking of using this to p/ex for the Nex but now I can't decide which one to keep, the EP2 or the Nikon D40 as a back up system. Will I get as good an image with the Nex as the D40? I like the idea of being able to use better lenses on the Nex with an adapter too. Help
