Goodbye D7000, hello EM5

I am about to make the same (okay, almost the same) move: selling my D7k and buying an E-pl5 in a few months. The OMD is for sure better, but I also want to rationalize the cost of my equipment. For me, the sensor is the key component (shooting a lot of astro/nighttime), this is the same in the pl5 and d7k. Besides, I will try underwater shooting - the pl5 already has the pt-ep10.
