Rob,
You may find that the mirrorless is so convenient and the quality so high, you may not want to carry a big DSLR again! Because of their ability to use so many lenses, they are so versatile. I have been adapting my Tamrons to the Pens and now that Tamron is in "the game" with the Sony mounts, my 50+ year old body is digging the light weight systems. I think that FF mirrorless and much higher megapixel sensors are coming soon too. I am glad that folks like Camera Land are getting in at the breaking edge!
