From Pro FF to OMD E-5

Hello, I wonder if some people in this forum were previously making pictures with faboulous full frame pro bodies... and sold them to use a mirrorless Olmypus OMD E-5

The optical viewfinder of these pro bodies are just fantastic to compose great pictures but carrying these pro machines can be a punishment.

Have some of you made the shift to a lighter machine without regretting it?

I am seriously considering the move but would appreciate to know if you have no regrets !

Thank you for your experience !
