Erik.....thanks for the update. Reading your post, I agree that you made the best decision. It is certainly well thought-out and the most important part of this decision is that you know what you want.
I love my Olympus E-M5. HOWEVER, there are times when my hands "itch" to play with a Canon dslr. I have to say, I would not go back, though. Even if I wanted to I can't carry heavy equipment anymore - my original reason for selling my gorgeous Canon lenses and going to M4/3. I haven't regretted it!
Also, I do get images comparable to what I got with the Canon "L" lenses.
I'm happy for you. I look forward to seeing more of your work.
