Traded my D90 to an EP-3 and now starting to ask why I did it.

Sorry to hear that. This is why whenever I buy a new camera I never sell the old one until I have had time to evaluate both together. The D90 is a really nice camera one of Nikons best endevors. I've owned the Nikon D40, D40X, D200, D5000 D90 and D5100 and of those the D40 and D90 are the only ones I still own.  I also have an OM-D EM-5 which I love but will never part with my D90 or D40. Maybe you'll learn to like the EP-3 or you'll find another D90.
